+ 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.
+ remove recursive-mutex definitions, finish threading demo for worm.c
+ remove a redundant adjustment of lines in resizeterm.c's
adjust_window() which caused occasional misadjustment of stdscr when
softkeys were used.
+ add 'O' (wide-character panel test) in ncurses.c to demonstrate a
problem reported by Sadrul H Chowdhury with repainting parts of
a fullwidth cell.
+ modify slk_init() so that if there are preceding calls to
ripoffline(), those affect the available lines for soft-keys (adapted
from patch by Clive Nicolson).
+ document some portability issues in man/curs_getyx.3x
