+ 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.
