ncurses 5.6 - patch 20070505

+ 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
