Sun Mar 15 03:46:50 1998 Dimitrie O. Paun <dimi@mail.cs.toronto.edu> * [*/*] Fixed some dprintf_ such that there is one and only one new line for each dprintf and that new line occurs at the end. Transformed some fprintfs into proper debug statements. Removed much redundancy from most of the debug statements. The redundancy appeared because now the component and function name is output automatically. Most debug statements also used to output the name of the function. All these changes prepared the source to switch completely to the new debugging interface. For more info, refer to ./documentation/debug-msg Sat Mar 14 19:45:23 1997 Andreas Mohr <100.30936@germany.net> * [misc/shell.c] [if1632/kernel.spec] Changed parameters of FUNC004() to fix a crash. Not sure if this fix is correct (doc wanted). * [windows/user.c] [if1632/user.spec] [include/user.h] Implemented UserSeeUserDo. * [msdos/int21.c] [include/msdos.h] Added "GET LIST OF LISTS" (INT 21/52h). Sat Mar 14 15:48:02 1998 Douglas Ridgway <ridgway@gmcl.com> * [include/windows.h] [relay32/gdi32.spec] [objects/enhmetafile.c] Beginnings of enhanced metafile support. Fri Mar 13 20:53:09 1998 John Richardson <jrichard@zko.dec.com> * [win32/console.c] Restart interrupted console writes. Fri Mar 13 18:59:24 1998 Matthew Becker <mbecker@glasscity.net> * [*/*.c] Updated documentation for API manpages. * [windows/dce.c] ReleaseDC16: Fixed cast. * [include/windows.h] [memory/virtual.c] VirtualQuery{Ex} should return DWORD instead of BOOL32. Fri Mar 13 13:03:06 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [README][documentation/status/] README updated, added lzexpand,version and multimedia status notes to new documentation/status directory. * [ole/*.c][if1632/typelib.spec] Added typelib stubs, several small additions and fixes. * [loader/pe_image.c] Fixed a small bug (fixup_imports got passed the wrong hModule in a remapcase). * [loader/signal.c][if1632/signal.c][misc/winsock_dns.c] [loader/module.c] Fixed some recursive debugger crashes (caused by invalid FS). * [misc/registry.c] Two bugs fixed.

Use timegm() where available. * [misc/lstr.c] Fix an off by one error in FormatMessage and handle the case when args = NULL (used by programs to get the length of the string). * [win32/console.c] Actual display a per-process Title string, better working attempt for WriteConsole32W and ReadConsole32W.
