+ add configure option --enable-weak-symbols to turn on new feature.
+ add configure-check for availability of weak symbols.
+ modify linkage with pthread library to use weak symbols so that
applications not linked to that library will not use the mutexes,
etc. This relies on gcc, and may be platform-specific (patch by Dr
Werner Fink).
+ add note to INSTALL to document limitation of renaming of tic library
using the --with-ticlib configure option (report by Dr Werner Fink).
+ document (in manpage) why tputs does not detect I/O errors (prompted
by comments by Samuel Thibault).
+ fix remaining warnings from Klocwork report.
+ modify _nc_panelhook() data to account for a permanent memory leak.
+ fix memory leaks in test/demo_menus
+ fix most warnings from Klocwork tool (report by Larry Zhou).
+ modify configure script CF_XOPEN_SOURCE macro to add case for
"dragonfly" from xterm #236 changes.
+ modify configure script --with-hashed-db to let $LIBS override the
search for the db library (prompted by report by Samson Pierre).
+ add new functions to lib_trace.c to setup mutex's for the _tracef()
calls within the ncurses library.
+ for the reentrant model, move _nc_tputs_trace and _nc_outchars into
the SCREEN.
+ start modifying test/worm.c to provide threading demo (incomplete).
+ separated ifdef's for some BSD-related symbols in tset.c, to make
it compile on LynxOS (report by Greg Gemmer).
+ modify configure check for libtool's version to trim blank lines
(report by sci-fi@hush.ai).
+ modify some modules to allow them to be reentrant if _REENTRANT is
defined: lib_baudrate.c, resizeterm.c (local data only)
+ eliminate static data from some modules: add_tries.c, hardscroll.c,
lib_ttyflags.c, lib_twait.c
+ improve manpage install to add aliases for the transformed program
names, e.g., from --program-prefix.
+ used linklint to verify links in the HTML documentation, made fixes
to manpages as needed.
+ fix a typo in curs_mouse.3x (report by William McBrine).
+ fix install-rule for ncurses5-config to make the bin-directory.
