Sun Nov  6 18:52:04 1994  Alexandre Julliard  (julliard@lamisun.epfl.ch)

	* [objects/oembitmap.c]  (New file)
	Added possibility to use .xpm files for OEM bitmaps.

	* [include/bitmaps/obm*]  (New files)
	Redrawn all OEM bitmaps in xpm format.

	* [objects/font.c]
	Add space for internal leading when using a negative font height.
	Stubs for AddFontResource() and RemoveFontResource().
	Fix in FONT_Init() for uninitialised default font.

	* [windows/dialog.c]
	Make font height negative as it is really a point size and not a
	pixel size; dialogs using 8-point fonts look better now.

	* [windows/graphics.c]
	Fixed the fix :-) for Pie() to make it work for Arc() and Chord() also.

	* [windows/nonclient.c]
	A few changes for new OEM bitmaps.

Sun Nov  6 18:22:18 1994  Michael Patra  <micky@marie.physik.tu-berlin.de>

	* [windows/class.c]
	The names of local classes have to be stored using GlobalAtom*.
	Otherwise they couldn't be accessed from other modules (e.g. BWCC) 

	* [if1632/call.S]
	CallTo16(cx): It's possible to set the contents of the cx-register.

	* [loader/ne_image.c]
	InitNEDLL(): The size of the local heap is now passed in the cx-
	register when initializing a DLL.

	* [memory/heap.c]
	LocalInit(): The case start==0 is now handled in the way it should.

	* [windows/win.c]
	GetWindowLong(): If the adress of the windows function is requested
	it's no longer returned if it's within the Wine code (and therefore
	unreachable by a windows program). This makes Borland's OWL happy.

	* [controls/edit.c]
	EDIT_GetStr(): Added handling for off<0.

Sun Nov  6 17:37:14 1994  Chris Jones  <chrisj@ichips.intel.com>

	* [loader/library.c]
	Fixed infinite loop bug when two DLLs refer to each other (fixes
	hangup of Quicken during loading).

Thu Nov 04 12:00:00 1994  Jan Willamowius  (jan@janhh.sh.sub.de)

	* [misc/dos_fs.c]
	Bug fix: The size of a disk an the available space
	is now returned in bytes instead of (incorrectly)
	KBytes.

Thu Nov 03 12:00:00 1994  Jan Willamowius  (jan@janhh.sh.sub.de)

	* [windows/graphics.c]
	Bug fix: Pie segments are now filled with correct brush.

Thu Nov  3 10:40:09 1994  Martin von Loewis  (martin@cs.csufresno.edu)

        * [Imakefile]
        generate rc.o before loader.o

        * [controls/menu.c]
        CopySysMenu: generate SYSMENU on the fly, eliminate hSysMenu

        * [include/resource.h]
        Add struct ResourceTable

        * [loader/bitmap.h]
        Load system bitmaps from sysresbmTable

        * [misc/clipboard.c]
          [windows/event.c]
        IsClipboardFormatAvailable,EVENT_SelectionRequest: bug fixes
        
        * [rc/Imakefile]
        generate rc.o from sysres.o and sysresbm.o. Added -lfl

        * [rc/rc.y]
        change style handling to allow ( S1 | S2 ) | S3

        * [rc/sysres.rc]
          [rc/sysresbm.rc]
        Put bitmaps and icons to sysresbm, everything else to sysres

        * [rc/winerc.c]
          [rc/winerc.h]
        Added -o, -c flags. New function set_out_file. Output to files.

        * [windows/dialog.c]
        DialogBoxIndirectPtr, DialogBoxIndirectParamPtr: New functions 

        * [windows/nonclient.c]
        Create AboutWine dialog from template pointer
