Alexandre Julliard a0b2b1d0f6 Release 971116
Sun Nov 16 07:42:44 1997  Alex Korobka <alex@trantor.pharm.sunysb.edu>

	* [windows/dce.c] [windows/clipboard.c] [windows/nonclient.c]
	Bug fixes.

	* [misc/shell.c] [resources/*]
	New "About" dialog.

Sat Nov 15 17:30:18 1997  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [configure.in] [Makefile.in]
	Replaced --with-library option by --disable-emulator. The default
 	is now to build both the library and the emulator.
	Renamed --with options to --enable to follow autoconf guidelines.

	* [loader/main.c] [miscemu/main.c] (New file)
	Split initialization in WinelibInit/EmulatorInit.

	* [loader/*.c]
	Removed all remaining #ifdef's WINELIB.

	* [controls/widgets.c] [windows/mdi.c]
	Converted MDIClientWndProc to 32-bit.

	* [debugger/break.c] [if1632/signal.c] [include/selectors.h]
	  [scheduler/thread.c]
	Code and data selector values are now computed at run-time.

	* [library/libres.c]
	Moved to loader/ directory.

	* [misc/main.c] [misc/version.c] (New file)
	Moved all version stuff to version.c. Cleaned up a bit.

	* [msdos/dpmi.c]
	Update the REALMODECALL structure on return from real-mode
	interrupt.

	* [windows/event.c] [windows/keyboard.c]
	Changed the way event coordinates are determined. Don't rely on
	the ConfigureNotify event values. This should fix all problems
	with cursor position in -desktop and -managed modes.

Sat Nov 15 16:09:36 1997  Slaven Rezic  <eserte@cs.tu-berlin.de>

	* [controls/button.c]
	(BUTTON_CheckAutoRadioButton): Prevent possible endless loop.

Wed Nov 12 03:42:45 1997  Chris Faherty <chrisf@america.com>

	* [misc/ver.c]
	Changed VerInstall32A to assume srcdir as destination if destdir
	is blank.  This was causing alot of DLL installation into SYSTEM
	directory to fail.

	* [loader/ne_image.c]
	NE_LoadSegment buffer[100] was too small and getting overruns.
	Changed it to buffer[200].

Sat Nov  8 06:09:57 1997  Len White <phreak@cgocable.net>

	* [misc/ddeml.c] [include/ddeml.h] [if1632/ddeml.spec]
	Added stub functions DdeConnectList(), DdeQueryNextServer(),
	DdeDisconnectList(), DdeSetUserHandle(), DdeAbandonTransaction(),
	DdePostAdvise(), DdeCreateDataHandle(), DdeAddData(), DdeGetData(),
	DdeAccessData(), DdeUnaccessData(), DdeEnableCallback(),
	DdeCmpStringHandles().

Fri Nov  7 19:44:26 1997  Olaf Flebbe  <o.flebbe@science-computing.de>

	* [files/directory.c]
	Fix typo in directory.c [broke loading of cdplayer on nt40]

	* [misc/main.c]
	Implemented -winver nt40.

	* [loader/resource.c] [user32.spec]
	Stubs for CopyAcceleratorTable, Destroy AcceleratorTable.

Thu Nov  6 22:37:04 1997  Morten Welinder  <welinder@rentec.com>

	* [files/drive.c]
	(GetDiskFreeSpace32A): Cap at 2GB.

	* [include/windows.h]
	Prototype DrawIconEx and CreateDIBSection32.
	Define OBM_RADIOCHECK.
	Add DI_* macros.

	* [objects/dib.c] [if1632/gdi.spec]
	CreateDIBSection is a WINAPI.  Renamed to CreateDIBSection32.
	Implement CreateDIBSection16.

	* [if1632/user.spec] [if1632/user32.spec]
	Add DrawIconEx.

	* [graphics/x11drv/text.c]
	(X11DRV_ExtTextOut): Change ascent and descent default to avoid
	zero-thinkness overstrike line.

	* [include/debugstr.h] [misc/debugstr.c]
	New files.

	* [msdos/dpmi.c]
	Don't prototype do_mscdex. In INT_Int31Handler, handle real-mode
	int 0x21, ah=0x52.

	* [msdos/int2f.c]
	Add dummys for 0x1681 and 0x1682.

	* [misc/registry.c]
	Fix memory leaks in RegDeleteKey32W.

	* [objects/text.c]
	In TEXT_NextLine, fix another off-by-one bug.

	* [include/bitmaps/obm_radiocheck]
	New file.  (It a small circle used to radio-button menu items
	when selected.)
	
	* [objects/oembitmap.c]
	Add obm_radiocheck.

	* [include/windows.h] [if1632/user32.spec] [controls/menu.c]
	  [if1632/user.spec]
	Define CheckMenuRadioItem{16,32}.  Define GetMenuItemRect{16,32}.

Wed Nov  5 11:30:14 1997  Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>
