Release 950817

Thu Aug 17 19:30:14 1995  Alexandre Julliard  <julliard@sunsite.unc.edu>

	* [*/Makefile.in]
	Removed winelibclean target, as it doesn't work anyway.

	* [controls/button.c]
	Avoid drawing the focus rectangle outside of the button.

	* [controls/widgets.c]
	Fixed bug with the size of the reserved bytes for the Edit
	control (caused Eudora to crash).

	* [debugger/*] [include/debugger.h]
	Unified debugger address handling. Segmented and linear addresses
	are no grouped in a single type DBG_ADDR.
	All commands now accept seg:off addresses.
	Module entry points are now loaded upon first entry to the
	debugger, so that entry points of the loaded executable also
	appear in the symbol table.

	* [include/registers.h] [miscemu/*.c]
	Register macros are now of the form 'AX_reg(context)' instead of 'AX'.
	This makes code less readable, but will prevent a lot of name
	clashes with other definitions. It also avoids a hidden reference
	to the 'context' variable.

	* [ipc/dde_atom.c] [misc/atom.c]
	All *AddAtom and *FindAtom functions now take a SEGPTR parameter,
	to allow supporting integer atoms.
	Moved atom.c to memory/ directory.

	* [loader/task.c]
	Fixed environment allocation to compute the size dynamically.
	Added 'windir' environment variable.
	Fixed GetDOSEnvironment() to return the current task environment.

	* [windows/message.c]
	Fixed bug in MSG_GetWindowForEvent().

Wed Aug  9 11:40:43 1995  Marcus Meissner  <msmeissn@faui01.informatik.uni-erlangen.de>

	* [include/ole.h]
	Added a lot of structures  from my Borland Manual. Neither complete,
	nor 100% right (check please)
	
	* [misc/shell.c]
	Fixed some of the Reg* functions.
	Enhanced ShellExecute.
	Please test: wine "regedit.exe /v" mplayer.exe soundrec.exe
	Do YOU know the format of \WINDOWS\REG.DAT? Mail me please :)

	* [misc/dos_fs.c]
	Make umsdos mounted windows dirs work again.

	* [miscemu/emulate.c]
	Added some comments, preimplementation of subfunction 7.

	* [multimedia/mmsystem.c]
	Implemented mciSendString. not complete, not clean, not
	necessarily working (only checked with a program which uses
 	'cdaudio' (one working program is cool.exe, a shareware waveditor
 	with cdaudio play facilities.)

	* [multimedia/mcicda.c]
	Segptr fixes in DriverProc
	Default cdrom drive in Linux is /dev/cdrom ... usually a symbolic
 	link to your real cdrom device.

Tue Aug  8 19:41:50 CDT 1995 Daniel Schepler <dks2@cec.wustl.edu>

	* [loader/resource.c]
	Don't crash in a LoadString to NULL

	* [loader/resource.c]
	Fixed accelerators to work with modifiers.  (ALT-x modifiers still
 	won't work unless the ALT keypress exited the menu.)

	* [misc/file.c]
	Expand a file to the current offset with an _lwrite of size zero.

	* [misc/file.c]
	Set a newly created file to read-write instead of write-only.
	
Sun Aug  6 20:28:35 1995  Anand Kumria <akumria@ozemail.com.au>

	* [misc/main.c] [include/msdos.h]
	Fixed to return DOS version 6.22, and the correct byte order
	for Windows programs.

Wed Aug  2 12:36:33 1995   Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>

	* [include/options.h] [memory/global.c] [misc/main.c]
	Make the new IPC run-time selectible, disabling it by default.
	(I think it's only useful for libwine, anyway.)

	* [loader/task.c] [memory/selector.c]
	In FreeSelector(), walk up the stack and fix the frames.

	* [objects/dib.c]
	Missing break statement in DIB_SetImageBits_RLE8().
	In GetDIBits(), set the compression flag in the bitmap info to zero.

	* [windows/dialog.c]
	GetNextDlgGroupItem() needs to treat the first child as if it had
	an implicit WS_GROUP bit set.

Mon Jul 31 15:44:47 EDT 1995 Louis-D. Dubeau <ldd@step.polymtl.ca>

	* [misc/dos_fs.c]
	Quick'n dirty fix for the initialisation of the Z: information
	structure.
