+ fix a bug in Ada95/samples/ncurses which caused a variable to become uninitialized in the "b" test. + fix Ada95/gen/Makefile.in adahtml rule to account for recent movement of files, fix a few incorrect manpage references in the generated html. + add Ada95 binding to _nc_freeall() as Curses_Free_All to help with memory-checking. + correct some functions in Ada95 binding which were using return value from C where none was returned: idcok(), immedok() and wtimeout(). + amend recent changes for Ada95 binding to make it build with Cygwin's linker, e.g., with configure options --enable-broken-linker --with-ticlib
