Patch from Erwann Chenede, #73900 fixing a lot of warnings with Forte CC,

Wed Mar 20 16:36:08 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/*.c: Patch from Erwann Chenede, #73900 fixing
        a lot of warnings with Forte CC, mostly implicit
        casts between void * and function pointers.

        * gdk/gdkevents.c (gdk_event_get_state): GdkEventVisibility's
        state field is not a GdkModifierType. (Also #73900)
