+ update release notes
+ minor build-fixes, mostly to test-package scripts
+ modify check for sizeof(wchar_t) to ensure it gives useful result
  when cross-compiling.
+ drop assumption in configure script that Cygwin's linker is broken.
+ define NCURSES_BROKEN_LINKER if the broken-linker feature is used,
  to simplify configure-checks for ncurses-examples.
+ reassert copyright on ncurses, per discussion in ncurses FAQ:
  https://invisible-island.net/ncurses/ncurses.faq.html#relicensed
+ modify comparison in make_hash.c to correct a special case in
  collision handling for Caps-hpux11
+ add testing utility report_hashing to check hash-tables used for
  terminfo and termcap names.
+ fix a missing prototype for _nc_free_and_exit().
+ update a few comments about tack 1.07
+ use an awk script to split too-long pathnames used in Ada95 sample
  programs for explain.txt

+   These notes are for ncurses 6.2, released February 12, 2020.
 
    This  release  is  designed  to  be source-compatible with ncurses 5.0
-   through  6.0; providing extensions to the application binary interface
+   through  6.1; providing extensions to the application binary interface
    (ABI).  Although  the  source  can  still be configured to support the
-   ncurses  5  ABI, the intent of the release is to provide extensions to
-   the ncurses 6 ABI:
-     * improve integration of tput and tset
-     * provide support for extended numeric capabilities.
+   ncurses  5  ABI, the reason for the release is to reflect improvements
+   to the ncurses 6 ABI and the supporting utility programs.
 
    There  are,  of  course,  numerous  other improvements, listed in this
    announcement.
 
-   The  release notes also mention some bug-fixes, but are focused on new
-   features  and  improvements  to  existing  features  since ncurses 6.0
-   release.
+   The  most  important  bug-fixes/improvements  dealt  with user-defined
+   capabilities  in terminal descriptions. The release notes also mention
+   some other bug-fixes, but are focused on new features and improvements
+   to existing features since ncurses 6.1 release.
 
   Library improvements
 
     New features
 
-   The  improved  integration of tput and tset made only small changes to
-   the  libraries.  However,  supporting  extended  numeric  capabilities
-   required a few changes:
-     * The  TERMINAL  structure  in  <term.h>  is  now opaque. Doing that
-       allowed  making the structure larger, to hold the extended numeric
-       data.
-       A   few   applications  required  changes  during  development  of
-       ncurses 6.1 because those applications misused the members of that
-       structure,   e.g.,   directly   modifying  it  rather  than  using
-       [13]def_prog_mode.
-     * Having  made  TERMINAL  opaque  (and  because  none of the library
-       functions  use  anything  except  a  pointer  to TERMINAL), it was
-       possible to increase the size of the structure, adding to the end.
-       Existing   applications  which  were  linked  to  the  ncurses 6.0
-       high-level   (ncurses,  ncursesw)  and  low-level  (tinfo,  tinfo)
-       libraries should not require re-linking since the binary interface
-       did  not  change,  nor  did  the  structure  offsets with TERMINAL
-       change.
-       A  few  applications use the inner TERMTYPE structure's offsets to
-       refer to terminfo capabilities within that structure. Again, those
-       do  not require modification because their offsets within TERMINAL
-       did not change.
-     * When configured for wide-characters, i.e., "ncursesw" the TERMINAL
-       structure is extended.
-       The  new  data in TERMINAL holds the same information as TERMTYPE,
-       but  with  larger  numbers  ("int"  versus  "short").  It is named
-       TERMTYPE2.
-       The  library  uses  this  structure  internally  in  preference to
-       TERMTYPE,   referring  to  TERMTYPE  only  to  initialize  it  for
-       applications that use the capabilities defined in <term.h>
-     * When  configured  for  8-bit  (narrow)  characters,  the TERMTYPE2
-       structure is not used.
-     * The updated application binary interface is 6.1.20171230 (used for
-       new  [14]versioned  symbols),  although the interface changes were
-       developed several months previously.
-
-   The  motivation  for  making  this  extension  came from noticing that
-   [15]termcap  applications  could  (though  not  [16]realistically) use
-   larger numbers than would fit in 16-bits, and the fact that the number
-   of  color  pairs  for  a  256-color  xterm  could  not be expressed in
-   terminfo  (i.e.,  32767  versus  65536). Also, a few terminals support
-   direct-colors, which could use the extension.
-
-   Generally  speaking,  applications  that  use  internal  details  of a
-   library  are unsupported. There was exactly one exception for ncurses:
-   the  tack  program  used  the internal details of TERMINAL, because it
-   provides  an  ncurses-specific  feature  for interactively modifying a
-   terminfo   description  and  writing  the  updated  description  to  a
-   text-file.  It  was  possible  to  not  only  separate tack from these
-   [17]internal  details  of  ncurses,  but  to generalize it so that the
-   program   works   with  Unix  curses  (omitting  the  ncurses-specific
-   feature). That was released as [18]tack 1.08 in July 2017.
-
-   While  making changes to tack to eliminate its dependency upon ncurses
-   internals,  the  publicly-visible  details  of  those  internals  were
-   reviewed,  and  some symbols were moved to private header files, while
-   others were marked explicitly as ncurses internals. Future releases of
-   ncurses  may  eliminate  some  of those symbols (such as those used by
-   tack 1.07) because they are neither part of the API or the ABI.
-
-   Using  the  TERMTYPE2 extended numeric capabilities, it is possible to
-   support  both  color  pair  values and color values past 32767. Taking
-   compatibility into account, developers readily understand that neither
-   function  signatures  nor  structure  offsets  change.  Also, existing
-   functions have to operate with the extended numbers. Most of that work
-   is  internal  to  the  library.  For the external interfaces, a hybrid
-   approach was used:
-     * X/Open  Curses  defined function prototypes such as wattr_set with
-       an  unused parameter, for "future" use. After 25 years, the future
-       is  here:  ncurses uses the parameter to augment color pair values
-       as described in the [19]manual page.
-     * Other  functions such as those defining color pairs did not have a
-       corresponding  reserved  parameter.  For  those,  ncurses  defines
-       extended  versions  such as init_extended_pair (versus init_pair),
-       init_extended_color (versus init_color).
+   There are several new features:
+     * O_EDGE_INSERT_STAY  tells  the  form  library  to optionally delay
+       cursor movement on a field edge/boundary
+     * O_INPUT_FIELD  extension to form library allows a dynamic field to
+       shrink if the new limit is smaller than the current field size.
+     * added  exit_curses  and  exit_terminfo to replace internal symbols
+       for leak-checking.
+     * added curses_trace, to replace trace().
 
    Additionally,  to  improve  performance other changes (and extensions)
    are provided in this release:
-     * Several  new  functions simplify management of large sets of color
-       pairs: reset_color_pairs, alloc_pair, find_pair and free_pair.
-     * New "RGB" extension capability for direct-color support is used to
-       improve performance of color_content.
-     * The  internal colorpair_t is now a struct, eliminating an internal
-       8-bit limit on colors
-     * Allocation  for  SCREEN's  color-pair table starts small, grows on
-       demand up to the limit given in the terminal description.
-     * setcchar and getcchar now treat a negative color-pair as an error.
+     * mouse  decoding  now handles shift/control/alt logic when decoding
+       xterm's 1006 mode
+     * ncurses  now  defines a limit for wgetnstr, wgetn_wstr when length
+       is negative or "too large".
+     * reordered  loop-limit checks in winsnstr in case the string has no
+       terminating null and only the number of characters is used.
+     * there  is  now  no  buffer-size  limit  when  reading the $TERMCAP
+       variable.
+     * the  $TERMCAP  variable  may  be  interpreted  as  a fallback to a
+       terminfo entry
+     * mvcur  now decides whether to use hard-tabs, using xt, tbc and hts
+       as clues.
+     * extended  colors  are  improved  by  modifying an internal call to
+       vid_puts  to pass extended color pairs e.g., from tty_update.c and
+       lib_mvcur.c
+     * the  initialization  functions  now  avoid relying upon persistent
+       data for the result from getenv
+     * scrolling is improved:
+          + a limit check in newline_forces_scroll handles the case where
+            the row is inside scroll-margins, but not at the end.
+          + improved loop limits in _nc_scroll_window handle a case where
+            the scrolled data is a pad which is taller than the window.
 
     Other improvements
 
-   These are new or revised features:
-     * modify  c++/etip.h.in  to  accommodate  deprecation  of  throw and
-       throws in c++17
-     * add new function unfocus_current_field
-     * add option to preserve leading whitespace in form fields
-     * add  a  macro  for is_linetouched and adjust the function's return
-       value  to  make  it possible for most applications to check for an
-       error-return.
-     * add  build-time  utility  report_offsets  to  help  show  when the
-       various configurations of tinfo library are compatible or not.
+   These are revised features:
+     * used  "const"  in  some prototypes rather than NCURSES_CONST where
+       X/Open  Curses  was updated to do this, e.g., wscanw, newterm, the
+       terminfo  interface.  Also  use  "const"  for  consistency  in the
+       termcap interface, which was withdrawn by X/Open Curses in Issue 5
+       (2007).  As  of  Issue  7,  X/Open  Curses still lacks "const" for
+       certain return values, e.g., keyname.
+     * modified  wbkgd  and  wbkgrnd  to  improve compatibility with SVr4
+       curses,  changing the way the window rendition is updated when the
+       background character is modified
+     * improved  terminfo  write/read by modifying the fourth item of the
+       extended  header  to  denote  the  number  of valid strings in the
+       extended string table (see term(5)).
+     * modified   the   initialization  checks  for  mouse  so  that  the
+       xterm+sm+1006  block  will  work  with  terminal  descriptions not
+       mentioning xterm.
 
    These were done to limit or ultimately deprecate features:
-     * drop  two  symbols  obsoleted  in  2004:  _nc_check_termtype,  and
-       _nc_resolve_uses
-     * move  _nc_tracebits,  _tracedump and _tracemouse to curses.priv.h,
-       since they are not part of the suggested ABI6.
-     * mark  some  structs  in  form/menu/panel  libraries as potentially
-       opaque without modifying API/ABI.
-     * ifdef'd     header-file    definition    of    mouse_trafo    with
-       NCURSES_NOMACROS
-     * remove  initialization-check  for calling napms in the term-driver
-       configuration; none is needed.
-     * modify trace to avoid overwriting existing file
+     * deprecated  safe-sprintf, since the vsnprintf function, which does
+       what was needed, was standardized long ago.
+     * marked   vwprintw  and  vwscanw  as  deprecated;  recommend  using
+       vw_printw and vw_scanw, respectively.
+     * added  deprecation warnings for internal functions called by older
+       versions of tack.
+     * removed unused _nc_import_termtype2 function.
 
    These are improvements to existing features:
-     * modify   make_hash   to  allow  building  with  address-sanitizer,
-       assuming that --disable-leaks is configured.
-     * move  SCREEN field for use_tioctl data before the ncursesw fields,
-       and  limit  that  to the sp-funcs configuration to improve termlib
-       compatibility
-     * modify db-iterator:
-          + ignore zero-length files in db-iterator; these are useful for
-            instance to suppress $HOME/.terminfo when not wanted.
-          + modify  update_getenv  to  ensure  that environment variables
-            which  are  not  initially  set  will  be checked later if an
-            application happens to set them
-     * modify  _nc_outc_wrapper  to use the standard output if the screen
-       was not initialized, rather than returning an error.
-     * improve  checks for low-level terminfo functions when the terminal
-       has not been initialized.
-     * modify set_curterm to update ttytype[] data used by longname/p>
-     * modify  _nc_get_screensize  to  allow  for  use_env and use_tioctl
-       state  to  be  per-screen  when  sp-funcs  are  configured, better
-       matching the behavior when using the term-driver configuration.
-     * remove an early-return from _nc_do_color, which can interfere with
-       data  needed  by  bkgd  when  ncurses  is configured with extended
-       colors
-     * incorporate A_COLOR mask into COLOR_PAIR, in case user application
-       provides an out-of-range pair number
-     * modify  logic for endwin-state to be able to detect the case where
-       the screen was never initialized, using that to trigger a flush of
-       ncurses'  buffer for mvcur, e.g., in the sample program dots_mvcur
-       for the term-driver configuration.
+     * check parameter of set_escdelay, return ERR if negative.
+     * check  parameter  of  set_tabsize,  return ERR if not greater than
+       zero
+     * correct  a status-check in _nc_read_tic_entry() so that if reading
+       a hex/b64 $TERMINFO, and the $TERM does not match, fall-through to
+       the compiled-in search list.
+     * amend check for repeat_char to handle a case where setlocale() was
+       called after initscr
+     * move macro for is_linetouched inside NCURSES_NOMACROS ifndef.
+     * use _nc_copy_termtype2 rather than direct assignment in setupterm,
+       in   case   it   is  called  repeatedly  using  fallback  terminfo
+       descriptions
+     * improve   workaround   for  Solaris  wcwidth  versus  line-drawing
+       characters
+     * add  checks  in repair_subwindows to keep the current position and
+       scroll-margins inside the resized subwindow.
+     * correct  a  buffer-limit  in  write_entry.c  for  systems that use
+       caseless filenames.
+     * improved build-time utility report_offsets:
+          + add categories, e.g., "w" for wide-character, "t" for threads
+            to  make the report more readable. Reorganized the structures
+            reported to make the categories more apparent.
+          + add  NCURSES_GLOBALS  and NCURSES_PRESCREEN to report to show
+            how similar the different libtinfo configurations are.
+     * modified  some header files to ensure that those include necessary
+       files except for the previously-documented cases
+     * added  some  traces  in  initialization to show whether a fallback
+       entry is used.
+     * made minor optimization to reduce calls to _nc_reserve_pairs
 
    These are corrections to existing features:
-     * fixes for writing extended color pairs in putwin.
-     * modify no-leaks code for lib_cur_term.c to account for the tgetent
-       cache.
-     * amend handling of the repeat_char capability in EmitRange to avoid
-       scope  creep:  translate  the character to the alternate character
-       set  when  the  alternate character set is enabled, and do not use
-       repeat_char for characters past 255.
-     * improve    wide-character    implementation    of   myADDNSTR   in
-       frm_driver.c,    which    was   inconsistent   with   the   normal
-       implementation.
-     * modify winnstr and winchnstr to return error if the output pointer
-       is  null,  as  well  as  adding a null pointer check of the window
-       pointer for better compatibility with other implementations.
-     * modify  setupterm  to  save  original  tty-modes so that erasechar
-       works  as expected. Also modify _nc_setupscreen to avoid redundant
-       calls to get original tty-modes.
-     * modify  wattr_set  and wattr_get to return ERR if win-parameter is
-       null, as documented.
-     * correct   order  of  initialization  for  traces  in  use_env  and
-       use_tioctl versus first _tracef calls.
-     * correct parameters for copywin call in _nc_Synchronize_Attributes
-     * flush  the  standard  output in _nc_flush for the case where SP is
-       zero,  e.g.,  when  called  via  putp. This fixes a scenario where
-       "tput flash" did not work after changes in 20130112.
-     * amend  internal  use  of  tputs  to consistently use the number of
-       lines  affected,  e.g.,  for  insert/delete  character operations.
-       While  merging terminfo source early in 1995, several descriptions
-       used  the "*" proportional delay for these operations, prompting a
-       change in doupdate.
-     * correct return-value of extended putwin.
-     * double-width  multibyte  characters  were  not counted properly in
-       winsnstr and wins_nwstr.
-     * amend  fix  for  _nc_ripoffline from 20091031 to make test/ditto.c
-       work in threaded configuration.
-     * modify _nc_viscbuf2 and _tracecchar_t2 to trace wide-characters as
-       a whole rather than their multibyte equivalents.
-     * minor  fix  in  wadd_wchnstr  to ensure that each cell has nonzero
-       width.
-     * move PUTC_INIT calls next to wcrtomb calls, to avoid carry-over of
-       error status when processing Unicode values which are not mapped.
-     * add missing assignment in lib_getch.c to make notimeout work
+     * fix  a  special  case  in  PutAttrChar  where  a cell is marked as
+       alternate-character  set,  but  the  terminal  does  not  actually
+       support the given graphic character. This would happen in an older
+       terminal such as vt52, which lacks most line-drawing capability.
+     * corrected  flag  for "seq" method of db 1.8.5 interface, needed by
+       toe on some of the BSDs.
+     * modify  comparison  in  make_hash.c  to  correct a special case in
+       collision handling for Caps-hpux11
+     * add    extended_slk_color{,_sp}   symbols   to   the   appropriate
+       package/*.{map,sym} files
+     * modify  lib_setup  to  avoid  calling pthread_self() without first
+       verifying that the address is valid, i.e., for weak symbols
+     * add  a  couple  of  broken-linker symbols to the list of versioned
+       symbols to help with link-time optimization versus weak symbols.
 
   Program improvements
 
-   While reviewing user feedback, it became apparent that the differences
-   between [20]reset (an alias for tset) and "tput reset" were confusing:
-     * one  ([21]tset)  updated the terminal modes, but used only part of
-       the terminfo capabilities for initialization, while
-     * the  other  ([22]tput) used all of the terminal capabilities while
-       neglecting the terminal modes.
-
-   On  further  investigation,  it  turned  out that the differences were
-   largely an accident due to the way those programs had evolved.
-
-   This  release  eliminates  the unnecessary differences, using the same
-   approach  for tput's init (initialization), reset and clear operations
-   as  the separate [23]reset and [24]clear programs. Doing this does not
-   change the command-line options; existing scripts are unaffected.
-
-   These  are the user-visible changes for the three programs (tput, tset
-   and clear):
-     * add  the  terminal-mode  parts  of "reset" (aka tset) to the "tput
-       reset"  command,  making  the  two  almost  the  same  except  for
-       window-size.
-     * improve  tput's  check  for  being  called as "init" or "reset" to
-       allow for transformed names.
-     * add "clear" as a possible link/alias to tput.
-     * amend changes for tput to reset tty modes to "sane" if the program
-       is  run  as  "reset",  like tset. Likewise, ensure that tset sends
-       either reset- or init-strings.
-     * add -x option to clear/tput to make the E3 extension optional
-     * add functionality of "tset -w" to tput, like the "-c" feature this
-       is not optional in tput.
-     * add  options  -T  and  -V  to clear command for compatibility with
-       tput.
-     * drop long-obsolete "-n" option from tset.
-     * modify tset's assignment to TERM in its output to reflect the name
-       by  which  the  terminal  description  is  found,  rather than the
-       primary  name.  That  was  an  unnecessary  part  from the initial
-       conversion  of  tset from termcap to terminfo. The termcap library
-       in 4.3BSD did this to avoid using the short 2-character name
-     * remove  a  restriction  in  tput's support for termcap names which
-       omitted capabilities normally not shown in termcap translations
-     * add usage message to clear command
-     * improve usage messages for tset and tput.
-
-   Other user-visible improvements and new features include:
-     * modify  tic/infocmp  display  of numeric values to use hexadecimal
-       when  they  are  "close" to a power of two, making the result more
-       readable.
-     * add "-W" option to tic/infocmp to force long strings to wrap.
-          + This  is in addition to the "-w" option which attempts to fit
-            capabilities into a given line-length.
-          + If  "-f"  option  splits  line,  do not further split it with
-            "-W".
-          + Begin a new line when adding "use=" after a wrapped line.
-     * add  "-q"  option  to infocmp to suppress the "Reconstructed from"
-       comment  from  the  header,  and  a corresponding option to tic to
-       suppress all comments from the "tic -I" output.
-     * Sorted options in usage message for infocmp, to make it simpler to
-       see unused letters.
-     * Updated usage message for tic, adding "-0" option.
-     * add infocmp/tic "-Q" option, which allows one to dump the compiled
-       form of the terminal entry, in hexadecimal or base64:
-          + A  "b64:"  prefix in the TERMINFO variable tells the terminfo
-            reader  to  use  base64  according  to  RFC-3548  as  well as
-            RFC-4648 url/filename-safe format.
-          + A   "hex:"   prefix  tells  the  terminfo  reader  to  accept
-            hexadecimal data as generated by "infocmp -0qQ1".
-
-   Other less-visible improvements and new features include:
-     * modify  utility headers such as tic.h to make it clearer which are
-       externals that are used by tack.
-     * add  "reset"  to  list  of  programs  whose  names might change in
-       manpages due to program-transformation configure options.
-     * modify  "-T" option of clear and tput to call use_tioctl to obtain
-       the operating system's notion of the screensize if possible.
-     * add  check  in  tput for init/reset operands to ensure those use a
-       terminal.
-     * modify  programs clear, tabs, tput and tset to pass the actual tty
-       file  descriptor  to  setupterm rather than the standard output or
-       error, making padding work.
-     * change  tset's initialization to allow it to get settings from the
-       standard  input  as  well  as  /dev/tty, to be more effective when
-       output or error are redirected.
-     * amend  check  in  tput,  tabs  and clear to allow those to use the
-       database-only  features  in cron if a "-T" option gives a suitable
-       terminal name.
-     * improve  error message from tset/reset when both stderr/stdout are
-       redirected to a file or pipe.
-
-   Several  of  the  less  apparent  features  deal  with  translation of
-   terminfo  to  termcap  (and the reverse), with corresponding checks by
-   tic:
-     * modify check in fmt_entry to handle a cancelled reset string. Make
-       similar fixes in other parts of dump_entry.c and tput.c
-     * correct  read of terminfo entry in which all strings are absent or
-       explicitly  cancelled.  Before  this  fix, the result was that all
-       were treated as only absent.
-     * modify   infocmp   to   suppress   mixture   of   absent/cancelled
-       capabilities that would only show as "NULL, NULL", unless the "-q"
-       option is used, e.g., to show "-, @" or "@, -".
-     * correct  a warning from tic about keys which are the same, to skip
-       over missing/cancelled values.
-     * add  check  in  tic for use of bold, etc., video attributes in the
-       color  capabilities,  accounting  whether the feature is listed in
-       ncv.
-     * add  check  in  tic for unnecessary use of "2" to denote a shifted
-       special key.
-     * improve  check  in tic for delays by also warning about beep/flash
-       when  a  delay  is not embedded, or if those use the VT100 reverse
-       video escape without using a delay.
-     * improve  checks  in trim_sgr0, comp_parse.c and parse_entry.c, for
-       cancelled string capabilities.
-     * add  check in tic for some syntax errors of delays, as well as use
-       of proportional delays for non-line capabilities.
-     * add  check  in  tic  for  conflict between ritm, rmso, rmul versus
-       sgr0.
-     * add  check  in _nc_parse_entry for invalid entry name, setting the
-       name to "invalid" to avoid problems storing entries.
-     * improve _nc_tparm_analyze, using that to extend the checks made by
-       tic  for  reporting inconsistencies between the expected number of
-       parameters for a capability and the actual.
-     * remove  tic  warning  about "^?" in string capabilities, which was
-       marked  as  an extension; however all Unix implementations support
-       this  and  X/Open  Curses  does not address it. On the other hand,
-       [25]BSD   termcap   did   not  support  this  feature  (until  the
-       [26]mid-1990s).
-       in  _nc_infotocap,  added  a check to ensure that terminfo "^?" is
-       not written to termcap.
-     * modify  sscanf calls in _nc_infotocap for patterns "%{number}%+%c"
-       and "%'char'%+%c" to check that the final character is really "c",
-       avoiding a case in icl6404 which cannot be converted to termcap.
-     * in  _nc_tic_expand and _nc_infotocap, improved string-length check
-       when  deciding  whether  to  use "^X" or "\xxx" format for control
-       characters, to make the output of tic/infocmp more predictable.
-     * limited  termcap  "%d" width to 2 digits on input, and use "%2" in
-       preference to "%02" on output.
-     * correct  terminfo/termcap  conversion of "%02" and "%03" into "%2"
-       and "%3"; the result repeated the last character.
+   Several improvements were made to the utility programs:
 
-    Examples
+   clear
 
-   Along  with  the library and utilities, many improvements were made to
-   the [27]ncurses-examples.
-
-   These changes were made to demonstrate new extensions in ncurses:
-     * add   demo_new_pair   program,   to   demonstrate  [28]alloc_pair,
-       [29]find_pair and [30]free_pair functions.
-       This  program  iterates  over  the  possible  color  combinations,
-       allocating  or  initializing color pairs. For best results, choose
-       screen-width dividing evenly into the number of colors. e.g.,
-
-     32x64,32x128   256 colors
-     24x44,24x88    88 colors
-     32x64,24x128   16 colors
-
-     * add  extended_color program, like the older color_set program, but
-       using   the   extended  color  functions,  with  and  without  the
-       SP-functions interface.
-     * add  picsmap  program  to  fill  in some testing issues not met by
-       dots,  using  this  as  the  third  example in a comparison of the
-       [31]ncurses versus slang libraries.
-       The   program  can  directly  read  X  bitmap  and  pixmap  files,
-       displaying  a  picture.  It  can  read  other  image  files  using
-       ImageMagick's convert program to translate the image into text.
-       For 16-, 88- and 256-color terminal descriptions, picsmap can load
-       a  palette file which tells it which color palette entries to use.
-       For direct-colors, the terminal descriptions use the RGB extension
-       capability.
+          + improved  logic  for  clearing with the E3 extension, in case
+            the  terminal  scrolls  content  onto  its saved-lines before
+            actually  clearing  the  display, by clearing the saved-lines
+            after clearing the display
 
-   There are other new example programs and a few scripts:
-     * add  dots_xcurses  program to illustrate a different approach used
-       for extended colors which can be contrasted with dots_curses.
-     * add  list_keys program show function keys for one or more terminal
-       descriptions.  It  uses  ncurses's  convention  of  modifiers  for
-       special keys, based on xterm.
-     * add  padview  program,  to compare pads with direct updates in the
-       view program.
-     * add sp_tinfo program to exercise the SP-functions extension of the
-       low-level terminfo library.
-     * add test-programs for termattrs and term_attrs functions.
-     * add  test_sgr  program  to  exercise  all  combinations of the sgr
-       capability.
-     * add   tput-colorcube   demo  script,  imitating  xterm's  88-  and
-       256-color scripts using tput.
-     * add  tput-initc  script  to  demonstrate  how  tput may be used to
-       initialize a color palette from a data file.
+   infocmp
+
+          + omit  filtering  of  "OTxx" names which are used for obsolete
+            capabilities,  when  the output is sorted by long-names. This
+            change helps when making a table of the short/long capability
+            names.
+
+   tic
+
+          + added   check   for   consistent   alternate   character  set
+            capabilities.
+          + added check for paired indn/rin.
+          + added check for terminals with parm_dch vs parm_ich.
+          + added  check  for  the  case  where setf/setb are given using
+            different   strings,   but   provide   identical  results  to
+            setaf/setab.
+          + corrected check for ich1.
+          + changed  a  too-large  terminal entry from a fatal error to a
+            warning.
+
+   toe
+
+          + ignores  any  hex/b64 $TERMINFO value in the list of terminfo
+            databases.
+
+   tset
+
+          + replace  check  in reset command for obsolete "pt" capability
+            using tbc and hts capabilities as clues
+          + modify reset to allow for tabstops at intervals other than 8.
+          + change   reset's   behavior   for  margins  to  simply  clear
+            soft-margins  if  possible,  rather  than  clearing  and then
+            setting them according to the terminal's width.
+
+   tput
+
+          + add "x" to getopt string so that "tput -x clear" works.
+
+   Several  changes were made to the generated ncurses*config scripts and
+   the   analogous   ".pc"   files  to  reduce  differences  between  the
+   configurations they report:
+     * modified the ncurse*-config and pc-files to more closely match for
+       the -I and -l options.
+     * filtered out linker-specs from the --libs report.
+     * amended  the ncurses*-config and pc-files to take into account the
+       rpath hack which differed between those files.
+     * modified  generated  ncurses*config  and  ncurses.pc, ncursesw.pc,
+       etc., to list helper libraries such as gpm for static linking.
+
+    Examples
+
+   Along  with  the  library and utilities, improvements were made to the
+   ncurses-examples.  Most  of  this  activity  aimed  at  improving  the
+   test-packages.  A few changes are more generally useful, e.g., for the
+   main   ncurses  test-program,  and  for  analyzing  traces  using  the
+   tracemunch script:
+     * improve  recovery  from  error  when  reading command-character in
+       test/ncurses.c, showing the relevant error message and not exiting
+       on EINTR.
+     * improve  tracemunch,  by keeping track of TERMINAL* values, and if
+       tracing  was first turned on after initialization, attempt to show
+       distinct screen, window and terminal names anyway.
+     * modify tracemunch to accept filename parameters in addition to use
+       as a pipe/filter.
+     * update  tracemunch  to  work  with  perl 5.26.2, which changed the
+       rules for escaping regular expressions.
+     * add some checks in tracemunch for undefined variables.
+     * modify TurnOn/TurnOff macros (in lib_vidattr.c and lib_vid_attr.c)
+       to avoid expansion of "CUR" in trace.
+
+   There are other new demo/test programs and reusable examples:
+
+   color_content
+          Demonstrate   the   color_content   and  extended_color_content
+          functions.
+
+   demo_tabs
+          A simple demo of tabs in curses.
+
+   dump_window
+          A  portable  curses screen-dump, used to compare ncurses screen
+          contents with Solaris.
+
+   pair_content
+          Demonstrate    the   pair_content   and   extended_pair_content
+          functions.
+
+   report_hashing
+          Check hash-tables used for terminfo and termcap names.
+
+   parse_rgb
+          Sample   implementation  of  the  ncurses  RGB  extension  from
+          user_caps.5, used in picsmap and savescreen programs.
 
    A  variety  of  improvements  were made to existing programs, both new
    features  as  well  as  options added to make the set of programs more
    consistent.
-
-   The  ncurses program is the largest; a proportionately large number of
-   changes were made to it:
-     * modify  a/A  screens to make exiting on an escape character depend
-       on  the start of keypad and timeout modes, to allow better testing
-       of function-keys.
-       add "t" toggle for notimeout function.
-     * modify layout of b/B screens to allow for additional annotation on
-       the  right  margin;  some  terminals  with partial support did not
-       display well.
-     * modify c/C screens to allow for extended color pairs.
-       add z/Z zoom feature to make extended color pairs easier to test.
-       modify  test-screens  to  take advantage of wide screens, reducing
-       the number of lines used for 88- and 256-colors.
-     * modify  "d"  edit-color  screen  to  optionally  read  xterm color
-       palette directly from terminal, as well as handling KEY_RESIZE and
-       screen-repainting with control/L and control/R.
-     * add examples to "F" screen for WACS_D_PLUS and WACS_T_PLUS.
-     * improve  "g"  screen,  correcting  ifdef which made the legend not
-       reflect  changes  to  keypad-  and  scroll-modes.  Added check for
-       return-value of putwin.
-     * make "s" test easier to understand which subtests are available
-       add a corresponding "S" wide-character overlap test-screen.
-     * add "v" screen to show baudrate and other values.
-
-   These changes were made to the other examples:
-     * modify  blue  program  to  use Unicode values for card-glyphs when
-       available, as well as improving the check for CP437 and CP850.
-     * improve   demo_menus   program,   allowing   mouse-click   on  the
-       menu-headers  to  switch  the  active  menu.  This  requires a new
-       extension option O_MOUSE_MENU to tell the menu driver to put mouse
-       events  which  do not apply to the active menu back into the queue
-       so that the application can handle the event.
-     * correct logic in demo_terminfo program for "-f" option
-     * modify  ditto program to allow $XTERM_PROG environment variable to
-       override "xterm" as the name of the program to run in the threaded
-       configuration.
-     * add several options to the "dots" test-programs.
-     * modify filter program:
-          + illustrate  an  alternative  to getnstr, that polls for input
-            while  updating  a  clock  on  the  right  margin  as well as
-            responding to window size-changes.
-          + adapt  logic  used in [32]dialog [33]"--keep-tite" option for
-            filter  program as the "-a" option. When set, filter attempts
-            to suppress the alternate screen.
-     * modify  knight  program  to  provide the "slow" solution for small
-       screens  using  "R", noting that Warnsdorf's method is easily done
-       with "a".
-     * modify  the  savescreen program to add test patterns that exercise
-       88-, 256-, etc., colors.
-     * add  options  to  test_arrays,  for selecting termcap vs terminfo,
-       etc.
-     * modify the view program:
-          + expand  tabs  using  the  ncurses  library rather than in the
-            test-program.
-          + eliminate the "-n" option by simply reading the whole file.
-          + implement page up/down commands.
-          + remove the very old SIGWINCH example; just use KEY_RESIZE.
-     * improve  animation  in  xmas  program  by  adding  a time-delay in
-       blinkit.
-     * modify  several  test-programs  which  call  use_default_colors to
-       consistently do this only if the "-d" option is given.
-     * modify the install-rule for ncurses-examples to put the data files
-       in the data directory, e.g., /usr/share/ncurses-examples.
-     * modify  several  test  programs  to  use  new popup_msgs function,
-       adapted from the help-screen used in the edit_field program.
-     * modify   test   data   for   xterm   palettes  to  use  the  newer
-       color4/color12 values.
-     * improve the tracemunch script:
-          + show screenXX pointers and thread identifiers as names.
-          + chang   address-parameters   of  add_wch,  color_content  and
-            pair_content to dummy parameters.
+     * add  "-l"  option to test/background, to dump screen contents in a
+       form that lets different curses implementations be compared.
+     * add  "@"  command  to  test/ncurses F-test, to allow rapid jump to
+       different character pages.
+     * added enum, regex examples to test/demo_forms
+     * amend  Scaled256() macro in test/picsmap.c to cover the full range
+       0..1000
+     * corrected  pathname used in Ada95 sample programs for explain.txt,
+       to  work  with  test-packages, and used an awk script to split the
+       resulting pathname when it would be too long for a single line.
+     * ignore  interrupted  system-call  in  test/ncurses's command-line,
+       e.g., if the terminal were resized.
+     * improved  ifdef's  for  TABSIZE  variable,  to  help with AIX/HPUX
+       ports.
 
   Terminal database
 
    There are several new terminal descriptions:
 
-     dumb-emacs-ansi,  dvtm,  dvtm-256color,  fbterm,  iterm2,  linux-m1
-     minitel    entries,    putty-noapp,    viewdata,   and   vt100+4bsd
-     building-block.
-
-     xterm+noalt,   xterm+titlestack,   xterm+alt1049,   xterm+alt+title
-     building  blocks  and  xterm+direct,  xterm+indirect, xterm-direct.
-     from [34]xterm patch #331.
-
-     several  other "-direct" descriptions to address the differences of
-     other terminal emulators versus xterm-direct.
+     alacritty,  domterm,  kitty,  mintty,  mintty-direct,  ms-terminal,
+     n7900,   nsterm-build309,  nsterm-direct,  screen5,  ti703,  ti707,
+     ti703-w, ti707-w vscode, vscode-direct, xterm-mono, xterm.js
 
    There  are  many  changes to existing terminal descriptions. Some were
    updates to several descriptions:
-     * use  xterm+sm+1006  in  several  terminal  descriptions which were
-       validated  as  supporting  the  extended  mouse  feature for their
-       respective terminal emulators.

+          + infocmp.1  explains  that the initial version of terminfo had
+            no  tool  for decompiling descriptions. That came later, with
+            SVr3, with a different developer.
+          + tabs.1 tells more than you wanted to know about the tool.
+          + tic.1  explains  that  the  initial version of terminfo had a
+            rudimentary  tool  (based  on termcap) for compiling entries.
+            The tool used with Unix was developed by others for SVr3.
+          + toe.1 explains the origin of this tool.
+     * Improvements for user_caps.5:
+          + mention meml, memu and box1
+          + expanded description of XM

+            screen's borders.
+          + tput.1 clarifies how tput determines the terminal size.
+
+   There  are  no new manual pages (all of the manual page updates are to
+   existing pages).
 
    Some  of  the  improvements  are  more subtle, relating to the way the
-   information is presented:
-     * Made minor fixes to manpage NAME/SYNOPSIS sections to consistently
-       use  rule  that  either  all  functions  which  are  prototyped in
-       SYNOPSIS  are  listed in the NAME section, or the manual-page name
-       is the sole item listed in the NAME section. The latter is used to
-       reduce  clutter,  e.g.,  for the top-level library manual pages as
-       well  as  for  certain  feature-pages  such  as  [85]SP-funcs  and
-       [86]threading.
-     * improve  manual  pages  for utilities with respect to POSIX versus
-       X/Open Curses.
-     * improve  organization  of  the [87]attributes and [88]color manual
-       pages.
+   information  is presented. For instance, the generated terminfo.5 file
+   uses  a  different  table  layout,  allowing  it  to use space on wide
+   terminals more effectively.
 
   Interesting bug-fixes
 
-     * modify  toe  to not exit if unable to read a terminal description,
-       e.g., if there is a permission problem.
-     * correct 20100515 change for weak signals versus sigprocmask
-     * work  around  Ada  tool-breakage in Debian 9 and later by invoking
-       gprconfig  to  specify  the C compiler to be used by gnatmake, and
-       conditionally   suppressing   Library_Options   line   for  static
-       libraries.
-     * There were, as well, several bug-fixes to handle illegal input for
-       tic.   Because   those  did  not  correspond  to  useful  terminal
-       descriptions, most users are unaffected.
+   While  there  were  many bugs fixed during development of ncurses 6.2,
+   only  a  few  (the  reason  for  this release) were both important and
+   interesting. Most of the bug-fixes were for local issues which did not
+   affect  compatibility across releases. Since those are detailed in the
+   NEWS file no elaboration is needed here.
+
+   The  interesting  bugs  were in tic/infocmp's handling of user-defined
+   capabilities.  These  were  not recent bugs. Initially it was a simple
+   problem:
+     * The  user-defined capabilities can be any type (boolean, number or
+       string),  but  once given a type all uses of the name must conform
+       to  that  type--unless  some  special  support  for  a  particular
+       multi-typed name is built into ncurses.
+     * One of simpleterm's contributors copied some definitions for using
+       tmux's user-defined capabilities in late in 2016.

+     * Later,  in (referring to a version from mid-2017), a user asked to
+       have it updated in ncurses.
+     * However,  it  had  an  error  from  the  change  in late 2016. The
+       terminal description made what tmux expected to be string actually
+       a boolean.
+       Over  the  years,  there  were  problems with each of simpleterm's
+       terminal  descriptions.  I  repaired those, and usually dealt with
+       the problem.
+     * The  difference  in this case was that when compiling the terminal
+       database, tic may have in memory the definitions for more than one
+       terminal  description  (so  that  it  can resolve "use=" clauses).
+       Seeing   two  different  types  for  the  same  name,  in  certain
+       situations  it  would  incorrectly merge the symbol tables for the
+       two terminal descriptions.
+     * On  simpleterm's  side,  their bug was finally fixed in late 2019,
+       three years after the bug was created.
+
+   For  ncurses,  the  elapsed  time  to fix this bug was less than three
+   years.  Someone reported a problem with the terminal description a few
+   weeks  after  releasing  ncurses 6.1 (in tmux #1264), and the terminal
+   description was updated that week (ncurses patch 20180224):
+
+20180224
+        + modify _nc_resolve_uses2() to detect incompatible types when merging
+          a "use=" clause of extended capabilities.  The problem was seen in a
+          defective terminfo integrated from simpleterm sources in 20171111,
+          compounded by repair in 20180121.
+        + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+
+   The larger part of that change added a check to prevent a simple merge
+   of  terminal  descriptions  where  the same user-defined name was used
+   with different types. But it raised some questions:
+     * Was  there  a  reliable  way to manage terminal descriptions which
+       used the same extended name in different ways?
+     * Should  ncurses  provide  a registry of well-known extended names,
+       with their types?
+
+   Since  the  correction to terminfo.src could have been readily adopted
+   by  packagers,  there  was  nothing  more  to  be  done  from ncurses'
+   standpoint  on that part. But improving ncurses to prevent issues like
+   that is the reason for making a release.
+
+   Nothing  more  (constructive) was mentioned with regard to simpleterm.
+   But  a  few  problems  were  found  in  the  handling  of user-defined
+   capabilities:
+     * Forward-references to user-defined capabilities in a "use=" clause
+       did  not  allocate  new  data  for  each  use.  In tic, successive
+       compilation   of   terminal   entries   could   add   user-defined
+       capabilities to the wrong terminal entry.
+       This  was  not noticed before, since xterm's terminal descriptions
+       were  the main users of the feature, and almost all of the uses of
+       the building-blocks which contained user-defined capabilities were
+       backward-references.
+     * There  is  one  (documented)  case  where  ncurses  6.1 supports a
+       user-defined  capability that could be any type (i.e., "RGB"). The
+       check  added  in February 2018 to guard against mismatches did not
+       handle all of the combinations needed.
+
+   Both  of  these  issues  dated  from  the  original  implementation of
+   user-defined  capabilities.  Fixing  them does not change the terminal
+   database, but a older tic without the fixes will not be able to handle
+   terminfo  sources  which rely upon those fixes. Starting in June 2019,
+   the  download  link  for  the  terminfo source file was capped at that
+   date. The development sources have an up-to-date copy of the file, for
+   people with a legitimate need for it.
+
+   The  "-c"  (check) option of tic is not very useful if it cannot offer
+   advice on parameters needed for user-defined capabilities. The various
+   Caps  files  were  reorganized to reduce redundancy, and in the common
+   portion  (Caps-ncurses),  a  registry  of user-defined capabilities is
+   provided for use by tic. While users can still define their own custom
+   capabilities,  tic  will not offer any advice when their parameters do
+   not match.
+
+   In  ncurses  6.2, tic makes a special check to allow any type for RGB,
+   but  its  being  able to do this relies upon fixes made in the ncurses
+   library in mid-2019.
 
   Configuration changes
 
     Major changes
 
-   This  release  provides  a new binary format for terminal descriptions
-   that  use  extended  numeric capabilities. Applications built with the
-   wide-character ncursesw library can use these extended numbers.
-     * This includes utilities such as tic and infocmp, because (as noted
-       in  [89]New features), the feature relies upon an extension to the
-       low-level tinfo library.
-     * A  few  software  packagers  use a configuration option of ncurses
-       which  allows the low-level tinfo library to be shared between the
-       high-level  ncurses  and  ncursesw libraries. This new feature was
-       designed to work in that configuration as well.
-
-   Other  applications (i.e., using the 8-bit ncurses library) which read
-   the  extended terminal descriptions see those numeric capabilities set
-   to the maximum value for a signed 16-bit number.
-
-   Older   versions   of   ncurses'   tic   accept  out-of-range  numeric
-   capabilities,  storing  those as the maximum value for a signed 16-bit
-   number.  Other  implementations of curses (mentioned in the discussion
-   of [90]picsmap) give zero for these out-of-range capabilities.
+   There  are  no  major  changes. Several new options were added to ease
+   integration  of packages with systems using different versions of GNAT
+   and ncurses. Also, improvements were made to configure checks.
 
     Configuration options
 
-   These  changes  provide  support  for  tack 1.08, released in [91]July
-   2017:
-     * add   --without-tack   configure  option  to  refine  --with-progs
-       configure option. Normally tack is built outside the ncurses tree,
-       but  a  few packagers combine it during the build. If term_entry.h
-       is installed, there is no advantage to in-tree builds.
-     * adjust   configure-script   to  define  HAVE_CURSES_DATA_BOOLNAMES
-       symbol  needed  for  tack  1.08  when  built  in-tree. Rather than
-       relying upon internal "_nc_" functions, tack now uses the boolean,
-       number  and  string capability name-arrays provided by ncurses and
-       SVr4  Unix  curses. It still uses term_entry.h for the definitions
-       of the extended capability arrays.
-     * add  dependency  upon  ncurses_cfg.h  to  tic's  header-files; any
-       program  using  tic-library  will have to supply this file. Legacy
-       tack  versions  supply  this  file;  ongoing  tack development has
-       dropped  the dependency upon tic-library and new releases will not
-       be affected.
-
-   Other changes to the configure-script and generated files include
-     * add  configure  options to disable checks for form, menu and panel
-       libraries  so  that  ncurses-examples  can  be built with non-SVr4
-       curses implementations.
-     * add  configure  option  --enable-opaque-curses for ncurses library
-       and similar options for the other libraries.
-     * add configure option --disable-wattr-macros for use in cases where
-       one   wants   to   use  the  same  headers  for  ncurses5/ncurses6
-       development,  by suppressing the wattr* macros which differ due to
-       the introduction of extended colors
-     * modify  configure macro for shared-library rules to use -Wl,-rpath
-       rather than -rpath to work around a bug in scons
-     * improve  ncurses-examples'  configure  script  to define as needed
-       NCURSES_WIDECHAR  for  platforms where _XOPEN_SOURCE_EXTENDED does
-       not  work.  Also  modified  the  test  program  to  ensure that if
-       building  with  ncurses,  that  the cchar_t type is checked, since
-       that  is  normally  (since [92]20111030) ifdef'd depending on this
-       test.
-     * modify  configure  script  to handle the case where tic-library is
-       renamed,  but  the  --with-debug  option is used by itself without
-       normal or shared libraries
-     * modify  editing  script which generates resulting.map to work with
-       the clang configuration on recent FreeBSD, which gives an error on
-       an empty "local" section.
-     * improve configure check for setting the WILDCARD_SYMS variable; on
-       ppc64 the variable is in the Data section rather than Text.
-     * correct  result  of  configure  option  --without-fallbacks, which
-       caused FALLBACK_LIST to be set to "no"
-     * modify  --with-pkg-config-libdir  option  to  make  it possible to
-       install  ".pc"  files  even if pkg-config is not found. Limit this
-       change,  to suppress the actual install if it is not overridden to
-       a valid directory at install time.
-     * disallow "no" as a possible value for --with-shlib-version option,
-       overlooked in cleanup-changes for [93]20000708.
+   There are a few new/modified configure options:
+
+   --with-config-suffix
+          helps  work  around  a  filename  conflict with Debian packages
+          versus test-packages.
+
+   --with-ada-libname
+          allows  one  to  rename  the  "AdaCurses" library (at least one
+          packager prefers a lowercase name).
+
+   --with-fallbacks
+          now ensures there is a value, and adds the fallback information
+          to top-level Makefile summary.
+
+   --with-pcre2
+          check for pcre-posix library to help with MinGW port.
+
+   --with-tic-path and
+
+   --with-infocmp-path
+          help  work  around  problems  building  fallback  source  using
+          pre-6.0 tic/infocmp.
+
+   --with-versioned-syms
+          option value can now be a relative pathname.
 
   Portability
 
    Many  of  the  portability  changes  are implemented via the configure
    script:
-     * improve  configure  script's  CF_CC_ENV_FLAGS  macro  to allow for
-       compiler  wrappers  such  as  ccache.  This  change moves only the
-       preprocessor,  optimization  and  warning  flags  to  CPPFLAGS and
-       CFLAGS,  leaving the residue in CC. That happens to work for gcc's
-       various   "model"  options,  but  may  require  tuning  for  other
-       compilers.
-     * modify  ncurses-examples'  configure  script to use pkg-config for
-       the  extra  form/menu/panel  libraries, to be more consistent with
-       the handling of the curses/ncurses library.
-     * add  configuration  checks  to build with [94]NetBSD curses, which
-       for example lacks [95]use_env.
-     * change  ncurses-examples  to use attr_t vs chtype to follow X/Open
-       documentation   more   closely   since  Solaris  xpg4-curses  uses
-       different  values for WA_xxx vs A_xxx that rely on attr_t being an
-       unsigned  short.  Tru64  aka  OSF1, HPUX, AIX did as ncurses does,
-       equating the two sets.
-     * modify  several  test  programs  to  reflect  that  ncurses honors
-       existing  signal  handlers in initscr, while other implementations
-       do not.
-     * add  configure  check  for  openpty to ncurses-examples' configure
-       script, for ditto.
-     * improve check for working poll function by using posix_openpt as a
-       fallback in case there is no valid terminal on the standard input
-     * modify  ncurses-examples'  configure  script  to check for pthread
-       dependency  of  ncursest  or  ncursestw  library when building the
-       ncurses examples, e.g., in case weak symbols are used.
-     * add   checks   in  ncurses-examples'  configure  script  for  some
-       functions neither in 4.3BSD curses, nor based on X/Open Curses:
-          + modify  a  loop limit in firework.c to work around absense of
-            limit checks in some libraries.
-          + fill the last row of a window with "?" in firstlast if waddch
-            does not return ERR on the lower-right corner.
-     * build-fixes for the Portland Group (PGI) compilers
-          + accept whitespace in sed expression for generating expanded.c
-          + modify  configure  check  that  g++ compiler warnings are not
-            used.
-          + add  configure  check  for  -fPIC  option  needed  for shared
-            libraries.
-     * modify  configure  script  for  clang  as used on FreeBSD, to work
-       around clang's differences in exit codes vs gcc.
-     * fixes for configure/build using clang on OSX
-          + do   not   redefine   "inline"  in  ncurses_cfg.h;  this  was
-            originally to solve a problem with gcc/g++, but is aggravated
-            by clang's misuse of symbols to pretend it is gcc.
-          + add  braces  to configure script to prevent unwanted addition
-            of "-lstdc++" option to the CXXLIBS symbol.
-          + improve/update  test-program  used  for checking existence of
-            stdc++ library.
-          + if $CXXLIBS is set, the linkage test uses that in addition to
-            $LIBS.
-     * fixes for OS/2:
-          + use  button  instead  of  kbuf[0]  in  EMX-specific  part  of
-            lib_mouse.c
-          + support building with libtool on OS/2
-          + use stdc++ library with OS/2 kLIBC
-          + clear  configure  script's  cf_XOPEN_SOURCE for OS/2, to work
-            with its header files
-     * add  "newer"  baudrate symbols to the [96]baudrate function in the
-       ncurses library as well as to a corresponding table in tset.
-     * modify ncurses-examples savescreen to work with AIX and HPUX.
-     * define WIN32_LEAN_AND_MEAN for MinGW port, making builds faster.
-     * add  a configure check for wcwidth versus the ncurses line-drawing
-       characters,  to  use  in  special-casing  systems such as Solaris.
-       Solaris,  however,  requires  a  special  case  that  maps Unicode
-       line-drawing  characters  into  the  acsc  string  for non-Unicode
-       locales.  Solaris also has a misconfigured wcwidth which marks all
-       of the line drawing characters as double-width.
-     * string-hacks (non-standard):
-          + fix  configure  script  to  record  when  strlcat is found on
-            OpenBSD.
-          + add   --enable-string-hacks   option   to   ncurses-examples'
-            configure script.
-          + completed  string-hacks  for  sprintf,  etc.,  including  the
-            ncurses-examples programs.
-          + make   --enable-string-hacks   option  work  with  Debian  by
-            checking   for   the   "bsd"   library   and  its  associated
-            "<bsd/string.h>" header.
-     * workaround for Debian's antique/unmaintained version of mawk:
-          + see  Debian  #65617,  which  was  fixed  in  mawk's  upstream
-            releases in [97]2009.
-          + related fixes when building link_test.
+     * ignore $TERMINFO as a default value in configure script if it came
+       from the infocmp -Q option.
+     * distinguish  gcc  from  icc  and  clang when the --enable-warnings
+       option   is   not   used,  to  avoid  unnecessary  warnings  about
+       unrecognized inline options
+     * consistently  prepend  new  libraries  as  they  are  found during
+       configuration,  rather  than  relying  upon  the linker to resolve
+       order dependencies of libraries.
+     * modified  configure  scripts  to  reduce  relinking/ranlib  during
+       library install :
+          + use  "install -p" when available, to avoid need for ranlib of
+            static libraries.
+          + scripts which use "--disable-relink;" add a 1-second sleep to
+            work around tools which use whole-second timestamps, e.g., in
+            utime rather than the actual file system resolution.
+     * add configure check for getenv to work around implementation shown
+       in  Emscripten  which overwrites the previous return value on each
+       call.
+       Use  that  to optionally suppress START_TRACE macro, whose call to
+       getenv may not work properly
+     * change  target configure level for _XOPEN_SOURCE to 600 to address
+       use of vsscanf and setenv.
+     * reduce  use of _GNU_SOURCE for current glibc where _DEFAULT_SOURCE
+       combines with _XOPEN_SOURCE
+       Allow  for  Cygwin's  newlib when checking for the _DEFAULT_SOURCE
+       symbol.
+       MidnightBSD   is   now   checked   for  the  _XOPEN_SOURCE-related
+       definitions.
+     * If the check for va_copy or __va_copy fails,
+          + configure  now  tries copying the pointers for va_list, or as
+            an array.
+          + alternatively, it checks for __builtin_va_copy(), which could
+            be used with AIX xlc in c89 mode.
+     * several changes to support a port to Ultrix 3.1:
+          + check if "b" binary feature of fopen works
+          + check for missing feature of locale.h
+          + add fallback for strstr() in test-programs
+          + add fallback for STDOUT_FILENO in test-programs
+     * The test/configure script (used for ncurses-examples) is improved:
+          + work around non-ncurses termcap.h file, e.g., in Slackware.
+          + check for TABSIZE variable.
+          + checks  for  the  X11/Intrinsic.h  header, accommodate recent
+            MacOS changes which largely emptied /usr/include.
+
+   Here are some of the other portability fixes:
+     * added  dummy  "check"  rule  in  top-level  and  test-Makefile  to
+       simplify building test-packages for ArchLinux.
+     * dropped   library-dependency   on  psapi  for  MinGW  port,  since
+       win_driver.c   defines   PSAPI_VERSION   to   2,   making  it  use
+       GetProcessImageFileName from kernel32.dll
+     * made  build-fixes  for  configuration  using --program-suffix with
+       Ada95,  noticed  with  MacOS  but  applicable  to  other platforms
+       without libpanelw, etc.
+     * modified  ncurses/Makefile.in  to  fix a case where Debian/testing
+       changes to the ld --as-needed configuration broke ncurses-examples
+       test packages.
+     * used   _WIN32/_WIN64   in  preference  to  __MINGW32__/__MINGW64__
+       symbols  to simplify building with Microsoft Visual C++, since the
+       former are defined in both compiler configurations.
