gtk/gdk/win32/gdkwin32.h
Tor Lillqvist 20b5d8ec2f More work on GDK for Win32. Still in an intermediate state. 
2000-07-23  Tor Lillqvist  <tml@iki.fi>

	More work on GDK for Win32. Still in an intermediate state.

	* gdk/makefile.cygwin
	* gdk/win32/makefile.cygwin: Removed.

	* gdk/makefile.mingw.in
	* gdk/win32/makefile.mingw.in: New files.

	* gdk/Makefile.am
	* gdk/win32/Makefile.am: Generate and distribute them.

	* gdk/win32/gdkwindow-win32.h
	* gdk/win32/gdkdrawable-win32.h
	* gdk/win32/gdkpixmap-win32.h: New files.

	* gdk/win32/gdkcolor-win32.c
	* gdk/win32/gdkcursor-win32.c
	* gdk/win32/gdkgc-win32.c
	* gdk/win32/gdkimage-win32.c
	* gdk/win32/gdkprivate-win32.h
	* gdk/win32/gdkwin32.h: Update data structures. Cosmetics:
	don't use fields and variables called xcursor, xid, etc (leftovers
	from the X11 backend).
