	* [Configure]
	Added compile-time option for IPC.

	* [configure.in]
	Added command-line options for language, IPC and malloc
	debugging.

	* [controls/menu.c]
	WM_MENUSELECT was sometimes sent to the wrong window.

	* [debugger/break.c]
	For the 'next' command, only step over instruction that require
	it. This allows 'next' to do the right thing with jmp and ret
	instructions.

	* [ipc/*.c] [memory/atom.c] [memory/global.c]
	IPC can now be configured out at compile-time.

	* [loader/task.c]
	Bug fix in TASK_Reschedule() that could cause a task to be deleted
	twice.

	* [miscemu/dosmem.c] (New file)
	Partial emulation of the BIOS data segment.

	* [miscemu/instr.c]
	Trap attempts to access selector 0x40 and remap the access to
	segment __0040H.

	* [tools/build.c]
	Fixed bug in CallTo32_LargeStack() that caused problems when
	compiling Wine with the -fomit-frame-pointer option.

	* [windows/message.c]
	Fixed bug in hardware event handling that could cause some events
	to get ignored.

Sat Aug 26 13:12:59 IST 1995 Michael Veksler <mveksler@vnet.ibm.com>

	* [ipc/README] [ipc/dde.tex]
	LaTeX documentation for the ipc and DDE stuff.

Wed Aug 23 22:01:23 GMT 1995 Michael Veksler <mveksler@vnet.ibm.com>

	* [ipc/Imakefile] [ipc/wine_test_stub.c]

	* [miscemu/int21.c]
	Misc fix to int21,ah=40 (write) to match _lwrite().
	AX=0x440A (check if handle is remote) added.

	* [multimedia/mmsystem.c]
	Moved mciSendString to mcistring.c.

	* [multimedia/mcistring.c]
	New file, string interface for MCI (not complete, not thoroughly
	tested).

	* [multimedia/audio.c]
	IOCTL prints errors; one paranoid check disabled.

	* [misc/file.c]
	Misc operator precedence fixes.

	* [if1632/gdi.spec] [objects/bitblt.c]
	Stub for FastWindowFrame (parameters not correct).

	In function MAPPING_FixIsotropic(), VportExt[XY] is multiplied by
 	the absolute value of (ydim / xdim) or (xdim / ydim).

Thu Aug 15 23:00:16  Gregory Trubetskoy  <grisha@mira.com>

	* [objects/oembitmap.c]
	Added some includes for Windows 95.
