+ > portability fixes for Ada95 binding:
+ + add configure check to ensure that SIGINT works with gnat. This is
+ needed for the "rain" sample program. If SIGINT does not work, omit
+ that sample program.
+ + correct typo in check of $PKG_CONFIG variable in Ada95/configure
+ + add ncurses_compat.c, to supply functions used in the Ada95 binding
+ which were added in 5.7 and later.
+ + modify sed expression in CF_NCURSES_ADDON to eliminate a dependency
+ upon GNU sed.
