Alexandre Julliard 530ee8407c Release 961023 
Tue Oct 22 20:09:52 1996  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [*/Makefile.in] [tools/makedep.c]
	New program to generate dependencies; should be faster and more
	portable than 'gcc -MM'.

	* [*/*]
	Replaced WPARAM and HDC by explicitly-sized types.

	* [windows/hook.c]
	Fixed bug in HOOK_GetHook16 function.

Thu Oct 17 09:13:50 1996  John Harvey <john@division.co.uk>

	* [include/debug.h] [include/stddebug.h]
        Added debug option for win16drv (-debugmsg +win16drv)

	* [graphics/win16drv/init.c]
        Only enable CreateDC if printer=on specified in wine section of
 	wine.conf.
 	printfs changed to dprintf_win16drv.
	Some tidying up.

	* [include/gdi.h] [graphics/x11drv/clipping.c]
	  [graphics/x11drv/Makefile.in]
        Moved SetDeviceClipping into drivers.
