Sat Aug 23 00:05:23 1997 Andreas Mohr <100.30936@germany.net> * [if1632/kernel.spec] [if1632/mmsystem.spec] Added some stubs. * [include/neexe.h] [loader/module.c] Added warning for OS/2 executables. * [multimedia/midi.c] Shortened MIDIOUT driver version string to be less than 31 chars. * [objects/gdiobj.c] Fixed DeleteObject32() to react properly when called with stock object. Fri Aug 22 18:03:26 1997 Dimitrie O. Paun <dimi@cs.toronto.edu> * [controls/updown.c] [include/updown.h] First attempt at implementiong the UpDown class. * [controls/widgets.c] Added the UpDown class to be initialized by InitCommonControls(). Wed Aug 20 18:01:33 1997 Doug Ridgway <ridgway@routh.UCSD.EDU> * [graphics/*] [objects/*] [include/gdi.h] Made all GDI objects (except DCs) moveable. Mon Aug 18 03:25:30 1997 Alex Korobka <alex@trantor.pharm.sunysb.edu> * [windows/event.c] [misc/winsock.c] [misc/winsock_dns.c] Removed IPC communication to speed up winsock services (tested only with 16-bit netscape 3.03). * [graphics/x11drv/xfont.c] [documentation/fonts] Miscellaneous improvements. Updated docs. Sun Aug 17 20:39:55 1997 Ingo Schneider <schneidi@informatik.tu-muenchen.de> * [misc/comm.c] A couple of bug fixes. Sun Aug 17 19:29:22 1997 Alexandre Julliard <julliard@lrc.epfl.ch> * [debugger/dbg.y] Display next instruction after stepi/nexti. * [if1632/relay.c] [include/callback.h] [tools/build.c] Replaced CallTo32_LargeStack with the CALL_LARGE_STACK macro for better Winelib support. * [include/sigcontext.h] Renamed to sig_context.h to avoid conflicts with libc. * [*/*] All API functions are now prefixed with WINAPI in prevision of future Winelib integration. * [loader/signal.c] [memory/ldt.c] Fixed assembly code to be -fPIC compatible. Thu Aug 14 14:38:15 1997 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [if1632/crtdll.spec][win32/except.c] _global_unwind, _local_unwind stub added. * [objects/dib.c] Don't read memory you don't even need for the target bitmap (fixes one 'lazy' program). * [if1632/relay.c][if1632/thunk.c][if1632/kernel32.spec] [win32/ordinals.c][memory/selector.c][memory/global.c] [include/callback.h] Added/moved some more win95 ordinal stuff. Implemented QT_Thunk (not 100% correct yet) and some friends. * [loader/pe_image.c] Add possibility to break at the DLL entrypoint. * [controls/static.c][misc/commdlg.c][scheduler/thread.c] Misc bugfixes and additions. * [misc/registry.c] The registry seems to be case-preserving but case-insensitive. * [memory/global.c] Adapted to new /proc/meminfo format. * [objects/font.c][graphics/x11drv/xfont.c] FONT_SelectObject and GetTextMetrics* get passed ranges in logical and not device points (thanks to Marion Reyzl for pointing this out). * [windows/caret.c] Use the windows own DC if present (The caret coordinates are logical coordinates based on it). Fixes another AMIPRO problem. Wed Aug 6 18:22:22 1997 Morten Welinder <terra@diku.dk> * [controls/menu.c] General clean-up and Win32 work: split item_flags into fType and fState; split item_id into wID and hSubMenu. Improved debug-printing. Implemented InsertMenuItem32[AW], SetMenuDefaultItem32, and SetMenuItemInfo32[AW]. Fixed GetMenuItemInfo32[AW]. * [if1632/user32.spec] Define above new functions. * [include/windows.h] Define MF_DEFAULT and MF_RIGHTJUSTIFY. Prototype above functions. * [include/menu.h] Don't prototype now-static MENU_InitSysMenuPopup. * [include/comm.h] Reduce MAX_PORTS to 9 (which the profile code can handle). Tue Aug 5 20:16:22 1997 Victor Schneider <vischne@ibm.net> * [library/winestub.c] [libtest/expand.c] These patches let people porting Windows apps compile them using the same conventions regarding global _argc and _argv as those on Windows C/C++ compilers.
