+ modify fix_wchnstr() in form library to strip attributes (and color)
from the cchar_t array (field cells) read from a field's window.
Otherwise, when copying the field cells back to the window, the
associated color overrides the field's background color (report by
Ricardo Cantu).
+ improve tracing for form library, showing created forms, fields, etc.
+ ignore --enable-rpath configure option if --with-shared was omitted.
+ add _nc_leaks_tinfo(), _nc_free_tic(), _nc_free_tinfo() entrypoints
to allow leak-checking when both tic- and tinfo-libraries are built.
+ drop CF_CPP_VSCAN_FUNC macro from configure script, since C++ binding
no longer relies on it.
+ disallow combining configure script options --with-ticlib and
--enable-termcap (report by Rong-En Fan).
+ remove tack from ncurses tree.
+ 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
