pixmap disappers

[matsu arch comp kyutech ac jp (Takashi Matsuda)]

With gtk+-971201, I can not display pixmap.
My environment is
	SunOS arch 5.5.1 Generic_103640-05 sun4u sparc SUNW,Ultra-1
	X11R6.3

As Patrice Fortier mentioned in gtk-fortier-971112-1.patch.README,
white pixel is 0 and black pixel is 1.
I restored gdkpixmap.c to the state that above patch is not applied,
and pixmaps were displayed.

It seems that clip mask is not interpreted as usual pixmap, just mask pattern.
In the gimp-0.99.15/app/interface.c (create_pixmap ()), I can see following
code.
	
      *mask = gdk_pixmap_new (parent, width, height, 1);
      gc = gdk_gc_new (*mask);
      gdk_draw_rectangle (*mask, gc, TRUE, 0, 0, -1, -1);

      tmp_color.pixel = 1;
      gdk_gc_set_foreground (gc, &tmp_color);
