Release 980301
Sun Mar 1 10:45:23 1998 Andreas Mohr <100.30936@germany.net>
* [loader/ne_image.c]
Fixed problem with weird DLLs (NE_FFLAGS_SINGLEDATA && DGROUP = 0).
* [msdos/dosmem.c]
Export address for __0000H, too.
* [msdos/dpmi.c]
Changed MemAlloc functions to return less fragmented addresses.
Sat Feb 28 18:50:12 1998 Alexandre Julliard <julliard@lrc.epfl.ch>
* [scheduler/process.c] [scheduler/sysdeps.c]
Don't use %fs register before threading initialization.
Sat Feb 28 14:04:56 1998 Kristian Nielsen <kristian.nielsen@risoe.dk>
* [configure.in] [include/acconfig.h]
Autoconf macro to check for non-reentrant X libraries.
* [windows/winpos.c]
In SetWindowPos32(), do not cause WM_SIZE messages when the
SWP_NOSIZE flag is specified. This fixes the division-by-zero in
Borland C++ 4.0 "Open Project" menu item.
Sat Feb 28 13:11:26 1998 James Moody <013263m@dragon.acadiau.ca>
* [ole/ole2nls.c]
Changed "English" values from German to English.
* [files/dos_fs.c]
Fixed off-by-one month bug.
Fri Feb 27 22:12:01 1998 Douglas Ridgway <ridgway@winehq.com>
* [windows/win.c]
Fix winelib class menu loading bug.
* [include/module.h] [loader/module.c]
LoadModule32 should be implemented in terms of CreateProcess.
* [programs/view/*]
Metafile viewer sample program.
* [documentation/wine.texinfo] [documentation/Makefile.in]
Improvements and additions, HTML target.

* [*/*]
Switched to the new debug messages interface. For more information
please refer to documentation/debug-msgs. Because the new scheme
introduces a new semantic level, I had to manually do through
about 530 dprintf_xxx! The rest of about 2400 where transformed
via a script. Because of the large number of changes that I had
to do, some may have not come out as nicely as I wanted them. If
this is the case, please let me know. There is a lot of work left
to do: -- a few hundred printf's to be converted -- about 2300
fprintf's to be converted -- about 600 FIXME's to be transformed
The problem is that in the above mentioned cases, a lot of manual
intervention is required because a lot of the information is
missing. There are also a lot of other things to be done to the
interface and so forth. I have now ideas for a at least a month
worth of full time work :) I will proceed with many changes in the
next few releases, so please do not start modifing things because
there will be a hell of a lot of conflicts. If you have ideas that
you want to integrate or you want to work on different things,
please coordinate with me.
Thu Feb 26 13:04:29 1998 David Lee Lambert <lamber45@egr.msu.edu>
* [ole/ole2nls.c] [include/windows.h]
First try at OLE date- and time-formatting functions.
Wed Feb 25 11:20:35 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>
* [files/*.c]
Changed dos device handling, added 'CON' devicehandling.
* [graphics/ddraw.c]
Bug fixes, some additions.
* [if1632/builtin.c][loader/module.c][library/winestub.c]
Small hack so we don't need a dummy BUILTIN_LoadModule
in winestub.c.
* [ole/*][relay32/ole32.spec][if1632/storage.spec]
storage.dll started. winword loads documents (saving
doesn't work yet, dunno why).
Several ole additions, some cleanups and bugfixes.
IMalloc16 implemented.
* [loader/pe_image.c]
Added some comments, fixed circular dll references,
fixed modref ordering, fixed tls allocation.
* [memory/global.c]
Added validity checks before every GET_ARENA_PTR.
(several functions rely on Global* return values
on invalid handles, like IsTask).
Implemented GlobalUnlockFree16.
* [memory/virtual.c]
Replaced dprintf_virtual by fprintf, so we can
do 'info map' again in the debugger. Increase read
linesize for Linux2.1 cases.
* [misc/cpu.c][misc/registry.c]
Moved cpu registry initialization to misc/cpu.c.
* [multimedia/dsound.c]
Enhanced, replaced GETOSPACE bufferingcheck by SETFRAGMENT.
* [relay32/crtdll.spec][relay32/ntdll.spec]
Replaced some ptr by respective 'str' and 'wstr' arguments
for libc functions.
* [scheduler/thread.c]
Added some sanity checks to stackallocation, tlshandling fixed.
* [tools/build.c]
Fixed cdecl argumenttype order (was reversed).
* [win32/ordinals.c]
Implemented KERNEL_449.
* [windows/dinput.c]
Some fixes, needs much more work. Tomb Raider2 works with keyboard ;)
Tue Feb 24 20:46:37 1998 James Juran <jrj120@psu.edu>
* [windows/win.c]
Fixed USER32 ordinal numbers in documentation.
Sat Feb 21 12:30:38 1998 John Richardson <jrichard@zko.dec.com>
* [files/file.c] [include/k32obj.h] [memory/virtual.c]
[scheduler/critsection.c] [scheduler/event.c] [scheduler/handle.c]
[scheduler/k32obj.c] [scheduler/mutex.c] [scheduler/process.c]
[scheduler/semaphore.c] [scheduler/thread.c]
Added generic k32obj read and write routines for k32objs that
support I/O.
* [documentation/console]
Updated console docs.
* [win32/console.c]
Make console work like a k32obj that supports I/O.
* [include/windows.h]
Make WriteFile and ReadFile take HANDLE32 for handle.
Sun Feb 15 14:07:07 1998 Dimitrie O. Paun <dimi@mail.cs.toronto.edu>
* [controls/menu.c] [misc/ver.c] [multimedia/dsound.c]
[multimedia/joystick.c] [windows/dialog.c]
Modified some dprintf_xxx's to prepare them for a new
dprintf_ scheme. Basically, I changed the dprintf's that
outputed a line with many dprintf calls to do just one
dprintf call.

- Now, we see that OPENFILE seem to have returned 0xFFFF (or -1). Checking
