SHORT-TERM TO-DO ITEMS:
develop a good set of regression tests to cover lib_doupdate.c and
lib_mvcur.c.
-+ Magic cookie support does not work, since the logic does not take into
- account refresh. Also, the initial optimize does not adjust the current
- location when a cookie is emitted.
++ Magic cookie support (for nonzero xmc values) does not work, since the logic
+ does not take into account refresh. Also, the initial optimize does not

+ Scrolling optimization has holes: for example, it forces repaints of the
screen between calls to refresh().
-+ SVr4 uses slightly different rules for determining when softkeys are shown.
++ SVr4 uses slightly different rules for determining when softkeys are shown.
For example, they are initially displayed (before the ncurses 'e' test
activates them), and a touchwin can apparently also force them to be
displayed.
+ The window classes defined in the c++ subdirectory need documentation. Some
C++ programmer could earn a lot of good karma by doing this...
-+ The resizeterm() function does not handle ripped-off lines such as that done
- for the slk_XXX functions.
++ vid_attr() should support the set_a_attributes (sgr1) string, but does not.
+ There appear to be no terminals that require that functionality.
+
++ the configure --disable-ext-funcs option does not work for Ada95 tree.
+
++ the --with-pthread configuration builds for Cygwin, but does not work
+ properly (test/worm.c shows all of the worms in the same location).
+
++ the --enable-rpath configure option builds for the corresponding platforms;
+ however combining it with --with-ticlib and --with-termlib does not always
+ produce libraries that can be run without setting environment variables.
+ Building those with libtool does not work either. (This is a problem with
+ the BSD platforms).
+
++ more work is needed to make the MinGW port support ordinary terminals.
Portability (or lack thereof):
trip over a known problem with the signal-handling code which causes abrupt
termination of ncurses applications following resume from a ^Z suspend (this
problem was first seen running lynx). You will not see this problem if you
- are running Linux or one of the 4.4BSD derivatives like FreeBSD, NetBSD, or
- BSDI. For details, see the analysis in the header comment of
- ncurses/tty/lib_tstp.c .

+ systems using that convention. For details, see the analysis in the header
+ comment of ncurses/tty/lib_tstp.c .
+ In theory, vwprintw and vwscanf are supposed to use the older varargs.h
- interface for handling variadic argument lists. Linux doesn't have
- varargs.h, it has the newer X/Open-standard stdargs.h equivalent. So these
- functions use stdargs instead. This is unlikely to be a problem unless
- you're building ncurses on a System V old enough to only have varargs.h.
- (Solaris 2.5.1 uses the stdarg.h binding as well).
-
-+ If you're using a BSD earlier than 4.4BSD, or a Linux old enough not to have
- a native vsscanf(3) in its library, vwscanw() will not work. You lose. (It
- should work on any System V, however). If you want to fix this, add an
+ interface for handling variadic argument lists (and are deprecated by X/Open
+ for that reason). Many newer systems do no have varargs.h, instead they have
+ only the newer X/Open-standard stdargs.h equivalent. So these functions use

implementation to ncurses/vsscanf.c.
