+ add use_window() and use_screen() functions, to develop into support
for threaded library (incomplete).
+ fix typos in man/curs_opaque.3x which kept the install script from
creating symbolic links to two aliases created in 20070818 (report by
Rong-En Fan).
+ corrected xterm+pcf2 terminfo modifiers for F1-F4, to match xterm
#226 -TD
+ split-out key_name() from MKkeyname.awk since it now depends upon
wunctrl() which is not in libtinfo (report by Rong-En Fan).
+ add a break-statement in misc/shlib to ensure that it exits on the
_first_ matched directory (report by Paul Novak).
+ add tack/configure, which can be used to build tack outside the
ncurses build-tree.
+ add --with-ticlib option, to build/install the tic-support functions
in a separate library (suggestd by Miroslav Lichvar).
+ modify configure script to omit the tic (terminfo compiler) support
from ncurses library if --without-progs option is given.
+ modify install rule for ncurses5-config to do this via "install.libs"
+ modify shared-library rules to allow FreeBSD 3.x to use rpath.
+ update config.guess, config.sub
