+ modify nc_tparm.h, adding guards against repeated inclusion, and
allowing TPARM_ARG to be overridden.
+ fix some strict compiler warnings in ncurses library.
+ quiet some pedantic gcc warnings.
+ modify _nc_wgetch() to check for a -1 in the fifo, e.g., after a
SIGWINCH, and discard that value, to avoid confusing application
(patch by Eygene Ryabinkin, FreeBSD bin/136223).
+ add configure script --enable-sp-funcs to enable the new set of
extended functions.
+ start integrating patches by Juergen Pfeifer:
+ add extended functions which specify the SCREEN pointer for several
curses functions which use the global SP (these are incomplete;
some internals work is needed to complete these).
+ add special cases to configure script for MinGW port.
+ modify makefile rules to allow clear, tput and tset to be built
without libtic. The other programs (infocmp, tic and toe) rely on
that library.
+ add/modify null-pointer checks in several functions for SP and/or
the WINDOW* parameter (report by Thorben Krueger).
+ fixes for field_buffer() in formw library (see Redhat Bugzilla
#310071, patches by Miroslav Lichvar).
+ improve performance of NCURSES_CHAR_EQ code (patch by Miroslav
Lichvar).
+ update/improve mlterm and rxvt terminfo entries, e.g., for
the modified cursor- and keypad-keys -TD
