Alexandre Julliard 44ed71f52f Release 971221 
Fri Dec 19 10:50:46 1997  Douglas Ridgway  <ridgway@winehq.com>

	* [Make.rules.in] [Makefile.in] [documentation/Makefile.in]

	Changed WIN_CreateWindowEx to allow child windows with zero
	width / height.

	HWND_TOPMOST to broadcast to all Win32 Windows.

	* [memory/virtual.c] [loader/pe_image.c]

	GetConsoleMode no longer returns ENABLE_WINDOW_INPUT and
	ENABLE_MOUSE_INPUT since these are not currently implemented.
