+    --with-wrap-prefix=XXX
+       When using the --enable-reentrant option, ncurses redefines variables
+       that would be global in curses, e.g., LINES, as a macro that calls a
+       "wrapping" function which fetches the data from the current SCREEN
+       structure.  Normally that function is named by prepending "_nc_" to the
+       variable's name.  The function is technically private (since portable
+       applications would not refer directly to it).  But according to one
+       line of reasoning, it is not the same type of "private" as functions
+       which applications should not call even via a macro.  This configure
+       option lets you choose the prefix for these wrapped variables.

+    5.7 (November 2, 2008)
+       Interface changes:
+
+       + generate linkable stubs for some macros:
+               getattrs
+
+       + Add new library configuration for tic-library (the non-curses portion
+         of the ncurses library used for the tic program as well as some
+         others such as tack.  There is no API change, but makefiles would be
+         changed to use the tic-library built separately.
+         
+         tack, distributed separately from ncurses, uses some of the internal
+         _nc_XXX functions, which are declared in the tic.h header file.
+
+         The reason for providing this separate library is that none of the
+         functions in it are suitable for threaded applications.
+
+       + Add new library configuration (ncursest, ncurseswt) which provides
+         rudimentary support for POSIX threads.  This introduces opaque
+         access functions to the WINDOW structure and adds a parameter to
+         several internal functions.
+
+       + move most internal variables (except tic-library) into data blocks
+         _nc_globals and _nc_prescreen to simplify analysis.  Those were
+         globally accessible, but since they were not part of the documented
+         API, there is no ABI change.
+
+       + changed static tables of strings to be indices into long strings, to
+         improve startup performance.  This changes parameter lists for some
+         of the internal functions.
+
+       Added extensions:
+
+       + add NCURSES_OPAQUE definition in curses.h to control whether internal
+         details of the WINDOW structure are visible to an application.  This
+         is always defined when the threaded library is built, and is optional
+         otherwise.  New functions for this:  is_cleared, is_idcok, is_idlok,
+         is_immedok, is_keypad, is_leaveok, is_nodelay, is_notimeout,
+         is_scrollok, is_syncok, wgetparent and wgetscrreg.
+
+       + the threaded library (ncursest) also disallows direct updating of
+         global curses-level variables, providing functions (via macros) for
+         obtaining their value.  A few of those variables can be modified by
+         the application, using new functions:  set_escdelay, set_tabsize
+
+       + added functions use_window() and use_screen() which wrap a mutex
+         (if threading is configured) around a call to a user-supplied
+         function.
+
+       Added internal functions:
+               _nc_get_alias_table
+               _nc_get_screensize
+               _nc_keyname
+               _nc_screen_of
+               _nc_set_no_padding
+               _nc_tracechar
+               _nc_tracemouse
+               _nc_unctrl
+               _nc_ungetch
+
+               These are used for leak-testing, and are stubs for
+               ABI compatibility when ncurses is not configured for that
+               using the --disable-leaks configure script option:
+
+               _nc_free_and_exit
+               _nc_leaks_tinfo
+
+       Removed internal functions:
+               none
+
+       Modified internal functions:
+               _nc_fifo_dump
+               _nc_find_entry
+               _nc_handle_sigwinch
+               _nc_init_keytry
+               _nc_keypad
+               _nc_locale_breaks_acs
+               _nc_timed_wait
+               _nc_update_screensize
+
+               Use new typedef TRIES to replace "struct tries":
+
+               _nc_add_to_try
+               _nc_expand_try
+               _nc_remove_key
