+ add manpages for summarizing public variables of curses-, terminfo-
and form-libraries.
+ minor fixes to manpages for consistency (patch by Jason McIntyre).
+ modify tic's -I/-C dump to reformat acsc strings into canonical form
(sorted, unique mapping) (cf: 971004).
+ add configure check for pthread_kill(), needed for some old
platforms.
+ modify initialization check for win32con driver to eliminate need for
special case for TERM "unknown", using terminal database if available
(prompted by discussion with Roumen Petrov).
+ for MinGW port, ensure that terminal driver is setup if tgetent()
is called (patch by Roumen Petrov).
+ document tabs "-0" and "-8" options in manpage.
+ fix Debian "lintian" issues with manpages reported in
http://lintian.debian.org/full/csmall@debian.org.html#ncurses
+ change test/ditto.c to use openpty() and xterm.
+ add locks for copywin(), dupwin(), overlap(), overlay() on their
window parameters.
+ add locks for initscr() and newterm() on updates to the SCREEN

+ begin table in curs_thread.3x manpage describing the scope of data
used by each function (or symbol) for threading analysis.
+ add null-pointer checks to setsyx() and getsyx() (prompted by
discussion by Martin v. Lowis and Jeroen Ruigrok van der Werven on
python-dev2 mailing list).
+ add null-pointer checks in set_term() and delscreen().
+ move _nc_windows into _nc_globals, since windows can be pads, which
are not associated with a particular screen.
+ change use_screen() to pass the SCREEN* parameter rather than
stdscr to the callback function.
+ force libtool to use tag for 'CC' in case it does not detect this,
e.g., on aix when using CC=powerpc-ibm-aix5.3.0.0-gcc
(report/patch by Michael Haubenwallner).
+ override OBJEXT to "lo" when building with libtool, to work on
platforms such as AIX where libtool supports only static libraries
(report/patch by Michael Haubenwallner).
+ add configure --with-pthread option, for building with the POSIX
thread library.
