        (wm_delete_window): If widget isn't a shell, use the parent.

        * xlwmenu.c (make_drawing_gcs): The scaling factor passed to
        `x_alloc_lighter_color_for_widget' is a float, not an int, and
        it's a multiplicative factor, so the name `delta' is inaccurate.
        Always base disabled foreground on the normal foreground.
        Don't use the temporary variable `temp'.

2002-04-19  Eli Zaretskii  <eliz@is.elta.co.il>

        * Makefile.in (TAGS): Don't use -t, it's the default behavior for
        etags, so it barfs if invoked with -t.

2002-03-17  Richard M. Stallman  <rms@gnu.org>

        * lwlib.c (P_): Definitions deleted.

2002-03-16  Eli Zaretskii  <eliz@is.elta.co.il>

2000-07-19  Gerd Moellmann  <gerd@gnu.org>
