Matthias Clasen 2a2d769d42 Make PLT-reduction work with gcc4, and don't include everything in
2005-03-15  Matthias Clasen  <mclasen@redhat.com>

	Make PLT-reduction work with gcc4, and don't include
	everything in gdkalias.h:

	* gdk/gdk.symbols: Group symbols by header and source file.
	* gdk/makegdkalias.pl: Protect definitions by the same
	preprocessor symbols used to guard the headers. Move
	the alias declarations to a separate file which is
	produced when calling makegdkalias.pl -def
	* gdk/Makefile.am (gdkaliasdef.c): Add a rule to generate this
	file.
	* gdk/*.c, gdk/x11/*.c: Include gdkalias.h after the other
	headers, include gdkaliasdef.c at the bottom.
