Alexandre Julliard 9ea19e54cb Release 970101 
Wed Jan  1 15:36:17 1997  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [controls/listbox.c]
	Use FindFirstFile/FindNextFile in LISTBOX_Directory.

	* [files/dos_fs.c]
	Rewrote FindFirstFile/FindNextFile to use DOSFS_FindNext().

	* [files/file.c] [files/directory.c]
	Use Win32 kernel objects and handles for file handles.
	Unified SearchPath() and OpenFile().

	* [loader/builtin.c]
	Moved to if1632/ directory.

	* [tools/build.c] [debugger/*] [miscemu/*]
	Win16 register functions now receive the same CONTEXT * structure
	as Win32 functions.

	* [include/sigcontext.h] [miscemu/instr.c]
	Added new macros to get register values from the SIGCONTEXT
	structure (only used for instruction emulation now).

	* [scheduler/process.c] [scheduler/thread.c] (New files)
	Allocate process and thread structures.

	* [scheduler/process.c] [win32/k32obj.c]
	Added Win32 kernel objects and handles management.

	* [loader/task.c]
	Create a Win32 process and thread for every Win16 task.

	* [misc/commdlg.c] [misc/shell.c] [windows/msgbox.c]
	Built-in resources are now in Win32 format. This also avoids
	16-bit callbacks for built-in dialogs.

	* [misc/lzexpand.c]
	Differentiate between 16-bit and 32-bit file handles.

	* [miscemu/int*.c]
	Moved all int emulation to msdos/ directory.

	* [msdos/*]
	New directory msdos/ contains all MS-DOS emulation code that can
	also be used for Winelib; this should enable Winelib apps to use
	DOS3Call and related functions.

	* [rc/winerc.c]
	A few bug fixes for Win32 resource format.

	* [windows/winpos.c]
	Hack in WINPOS_ReorderOwnerPopups() to avoid X crashed (still not
	right though).

Sun Dec 29 17:47:55 1996  O. Flebbe <flebbe@science-computing.uni-tuebingen.de>

	* [loader/pe_image.c]
	Make sure BSS of a PE_Image is zero.

Sat Dec 28 22:15:34 1996 Alex Korobka <alex@trantor.pharm.sunysb.edu>

	* [windows/scroll.c]
	ScrollWindowEx() rewrite, ScrollDC() fix.

	* [windows/nonclient.c] [controls/menu.c]
	Fixed Alt-Space crashes in dialogs.

	* [windows/event.c] [windows/message.c]
	Some changes in mouse message generation.

Thu Dec 26 09:25:24 1996  Philippe De Muyter  <phdm@info.ucl.ac.be>

	* [debugger/stabs.c]
	Dummy DEBUG_ReadExecutableDbgInfo provided for !__ELF__ case.

Tue Dec 24 00:59:05 MET 1996  Martin Buck <martin-2.buck@student.uni-ulm.de>

	* [windows/event.c]
	Changed XK_Page_{Up,Down} to XK_{Prior,Next} for X11R5
	compatibility.
