Fix memory leak. (#74400, Morten Welinder.)

Fri Mar 22 10:56:19 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkaccelmap.c (gtk_accel_map_save_fd): Fix memory
        leak. (#74400, Morten Welinder.)

        * gtk/gtkaccelmap.c: Properly handle short returns from
        write() calls. (Handling EINTR isn't enough... that only
        handles the case where you were interrupted before you
        wrote a single byte.)

        * gdk/linux-fb/gdkmouse-fb.c gdk/linux-fb/gdkkeyboard-fb.c:
        Robustify against short returns from write() calls.
