gtk/gdk/win32/gdkwindow.c
Tor Lillqvist d142187b38 Fixes to the win32 backend to actually be able to compile within a 
directory hierarchy like this, with common gdk.h and gdktypes.h
for all backends. gdkrectangles.c and gdkrgb.c is copied before
compilation from the x11 backed (which still is in .., but
eventually will be in ..\x11).
