gcc -mno-cygwin (egcs-1.1.2) on cygwin-b20.1. * gdk/win32/makefile.cygwin gtk/makefile.cygwin: New files. * config.h.win32: Changes for gcc. * gdk/gdkrectangle.c: Include gdk.h as <gdk/gdk.h>. * gdk/gdkcolor.c: config.h.win32 already defines strcasecmp. * gdk/win32/gdkconfig.h: Only the MS compiler has wctype.h. * gdk/win32/gdkdnd.c: Protect (unused) OLE2 stuff better. Protect shl stuff unavaiilable with mingw32 headers. * gdk/win32/gdkevents.c: Fix typo. * gdk/win32/gdkglobals.c: Use GDKVAR here also for gcc. * gdk/win32/gdkim.c: Use OEM code page for multibyte chars. (?) * gdk/win32/gdkinput.c: Use __try __except only with the MS compiler. * gdk/win32/gdkprivate.h: Make up for some stuff missing from the mingw32 headers. * gdk/win32/makefile.msc: Use latest Wintab kit and glib. * gtk/gtkfilesel.c: Include <glib.h> early, to get stat->_stat definition on Win32. Test for NATIVE_WIN32, not _MSC_VER. * gtk/gtkfontsel.c: Protect CHARSET redefinition on Win32. Test for NATIVE_WIN32, not _MSC_VER. * gtk/gtkmain.c: No use warning about developer version on Win32, there aren't any non-developer versions anyhow. * gtk/gtkrc.c: Test for NATIVE_WIN32, not _MSC_VER. * gtk/makefile.msc: Use pthread from another directory. Minor other changes.
