ncurses 5.9 - patch 20111022

+ correct logic for discarding mouse events, retaining the partial
  events used to build up click, double-click, etc, until needed
  (cf: 20110917).
+ fix configure script to avoid creating unused Ada95 makefile when
  gnat does not work.
+ cleanup width-related gcc 3.4.3 warnings for 64-bit platform, for the
  internal functions of libncurses.  The external interface of courses
  uses bool, which still produces these warnings.
