	Removed HWND type.

Fri Feb 14 15:09:19 1997  Onno Hovers <onno@stack.nl>

	* [memory/global.c]
	Implemented GMEM_MOVEABLE blocks for Win32.

Fri Feb 14 00:24:39 1997  Alex Korobka <alex@trantor.pharm.sunysb.edu>

	* [loader/task.c] [windows/queue.c]

	* [misc/lstr.c]
	Fixed CharPrev32A().

	* [windows/hook.c] [include/hook.h]
	Restored broken WH_CALLWNDPROC functionality for dialogs, etc...

	* [windows/win.c] [windows/defwnd.c] [windows/mdi.c]
	  [windows/event.c] [controls/edit.c] 
	Added WIN_ISWIN32 flag to windows created by Win32 calls. 
	Several new Win32 messages are sent when this flag is on.
	
	* [msdos/dosmem.c] [memory/global.c]
	Some changes in DOS memory allocation.

Fri Feb  7 21:46:03 1997  Andrew Taylor  <andrew@riscan.com>
