Release 980118
Sun Jan 18 17:05:58 1998 Alexandre Julliard <julliard@lrc.epfl.ch>
* [include/stackframe.h] [tools/build.c]
Some cleanups in stack frame building.
* [misc/port.c]
Implemented clone() wrapper for libc5 users.
* [scheduler/mutex.c] [scheduler/synchro.c]
Implemented abandoned mutexes.
* [scheduler/process.c] [scheduler/thread.c]
We now create a process and a thread structure as soon as possible
during initialization.
* [scheduler/thread.c] [scheduler/sysdeps.c]
Moved system-specific thread handling to sysdeps.c.
Fri Jan 16 10:45:15 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>
* [graphics/ddraw.c][include/ddraw.h]
Surface handling enhanced. Some stuff already works ;)
* [multimedia/dsound.c][include/dsound.h]
Implemented using the Open Sound System.
Slowly starts to work (sounds terrible for some programs).
* [configure.in][multimedia/audio.c][include/config.h.in]
Added check for OpenSoundSystem, fixed -lXxf86dga check.
Replaced OS #ifdefs by #ifdef HAVE_OSS in mm/audio.c.
* [if1632/relay.c][relay32/relay386.c]
Do not print control characters for 'str' or 'wstr' args.
* [misc/registry.c]
"" seems to equals NULL in keynames. Replace where needed. Seems
to help the win95 regedit.exe...
* [win32/newfns.c]
Implemented QueryPerformance* using gettimeofday(2)
(should be done using the pentium timers probably).
* [tools/ipcl]
Removed useless open_pipe construct.

* [objects/region.c] [include/region.h] [graphics/x11drv/clipping.c]
Regions are now internal to Wine. The basis of this code is taken
from the X11 distribution. GetRegionData() is implemented as is
ExtCreateRegion() (without Xforms). CreatePolyPolygonRgn() should
behave correctly now.
* [objects/metafile.c] [graphics/metafiledrv/graphics.c]
[graphics/metafiledrv/init.c] [include/metafile.h]
[include/metafiledrv.h]
Playback of META_CREATEREGION should now work. Implemented recording
of META_CREATEREGION and META_PAINTREGION.
* [graphics/x11drv/graphics.c]
FillRgn() (and therefore its friends) respect logical co-ords.
Wed Jan 7 01:21:45 1998 Steinar Hamre <steinarh@stud.fim.ntnu.no>
* [configure.in] [include/acconfig.h] [tools/build.c]
Now checking whether to use .string or .ascii.
* [configure.in] [include/acconfig.h] [scheduler/critsection.c]
Defining union semun if this is not available from header files.
* [misc/lstr.c]
Moved wine's own header files below <wctype.h> to avoid
parse error on Solaris.
Sun Jan 4 15:38:07 1998 Andrew Taylor <ataylor@cadvision.com>
* [multimedia/mmsystem.c] [multimedia/mmio.c]
Implemented mmioSendMessage and rearranged the mmio
subsystem in terms of this function.
Wed Dec 24 00:51:29 1997 Charles Duffy <cduffy@bigfoot.com>
* [windows/clipboard.c] [relay32/user32.spec]
GetPriorityClipboardFormat32 now has something other than just
a stub. I have no idea if it works (can't test until
SetClipboardData is finished) but HEdit likes things a lot more
this way.
