wxWidgets/include/wx/gtk/dcclient.h
Vadim Zeitlin 72cdf4c9b3 1. wxApp::ProcessPendingEvents() is now common, added appcmn.cpp and
regenerated the makefiles. wxPostEvent() should work for wxGTK too (untested)
2. long -> wxCoord change for wxGTK and wxMSW, use
   wxUSE_COMPATIBLE_COORD_TYPES to get the old behaviour
3. wxHTML compilation fixes (for !wxUSE_HTML case)
4. a couple of handy macros in thread.h added
