	* loader/selector.c (FixupFunctionPrologs): 
	New function to fixup loaded DLL function prologs.  It replaces the
	do nothing code with code that loads DS with the appropriate data
	segment for the DLL.

	* misc/cursor.c (LoadCursor): 
	Disabled cursor loading from .EXE or .DLL.  The code needs to handle
	the possibility of multiple cursors in a single directory.  Also,
	it should check to see if the cursor is the right size.

	* objects/font.c (EnumFonts): 
	Checked for lpLogFontList[i] == NULL

	* objects/gdiobj.c (SetObjectOwner): 
	Removed stub.  Replaced with simple return in gdi.spec.  This
	function is not defined for the retail version of Windows.

	* memory/heap.c (WIN16_LocalHandleDelta): 
	New function.  This is really a dummy that imitates the proper
	return values.

	* loader/library.c (GetProcAddress): 
	Fixed definition of IS_BUILTIN_DLL() macro.

Mon Jun  6 18:15:40 1994  Bob Amstadt  (bob@pooh)

	* miscemu/int21.c (SeekFile): 
	Needed to return current position in DX:AX.

	* windows/utility.c (windows_wsprintf): 
	Added support for '#' in format, and fixed bug with "ptr" being
	incremented too many times.

	* miscemu/int21.c (OpenExistingFile): 
	Add code to handle opening files read-only and write-only.

	* loader/wine.c:
	Segment fixups now done in LoadImage instead of _WinMain.  This
	is necessary to support LoadLibrary().

	* [loader/*]
		- fixed: GetModuleHandle() sometimes returned
		  a wrong handle.
		- don't init dlls when cs == 0 (lzexpand, doesn't
		  seem to have a init function)
		- LoadLibrary & LoadImage now return error instead
		  of stopping wine.
		- moved most of NE-functions into one file.
		- LoadLibrary() uses w_files list instead of its
		  own list.
		- NE exectables are now fixed-up and initialised when
		  loaded instead of only once before calling InitTask.

	* [miscemu/int15.c] [miscemu/int31.c]
	Added.	

	* [loader/selector.c]
	Stubs added for {Get|Set}SelectorLimit(), {Get|Set}SelectorBase().

	* [misc/main.c]
	Stub added for IsRomModule().

	* [miscemu/int21.c]
	Some cleanup, added heap for returning data.

Jun 6, 94 martin2@trgcorp.solucorp.qc.ca (Martin Ayotte)

	* [tools/build.c]
	Change MAX_ORDINALS	define to higher value, 1299 entries.
	(MMSYSTEM doesn't have succesive numbers, some are around 1200).

	* [windows/utility.c]
	Bug fix in windows_wsprintf(), (twice increments ...).

	* [windows/winpos.c]
	Bug fix in SetWindowPos(), redraw was done if flag
		was set to SWP_NOREDRAW while SWP_SHOWWINDOW).

	* [misc/message.c] [controls/combo.c]
	Add an InvalidateRect() in WM_SHOWWINDOW to statisfy the new 'saveunder'.

	* [windows/win.c]
	In CreateWindowEx(), do SetMenu() calls after window creation,
		just before sending to WM_NCCALCSIZE.

	* [controls/menu.c]
	In function SetMenu(), now use SetWindowPos() with 
		flags SWP_FRAMECHANGED to readjust menu area.
	Function MenuBarCalcSize() redone.

        * [objects/text.c]
        Fixed problems associated with DT_WORDBREAK flag.  String length
        was not being properly decremented when lines were folded, and
        wrapping was not performed when DT_NOCLIP and DT_NOPREFIX were
        both on in addition to DT_WORDBREAK.  Windows does wrapping in
        this case, and now so does wine.

Sun Jun  5 19:17:49 1994  Olaf Flebbe  (olaf@dragon)

        * [edit.c]
        cp1 was uninitialized iff lineno == 0

        *  FindFile tests for existance of file even if a full
           filename was supplied. What about unix file names?

        * [controls/listbox ]
        wndPtr was uninitialized for LB_SETTOPINDEX

        * [misc/property.c]     
        Do not free lpProp. Is it really allocated by malloc?
	{edited by Bob Amstadt: changed free() to GlobalFree()}
