Make PLT-reduction work with gcc4, and don't include everything in

2005-03-14  Matthias Clasen  <mclasen@redhat.com>

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

	* gdk-pixbuf.symbols: Group symbols by header and source file.
	* /makegdkpixbufalias.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 makegdkpixbufalias.pl -def
	* Makefile.am (gdk-pixbuf-aliasdef.c): Add a rule to generate
	this file.
	* *.c: Include gdk-pixbuf-alias.h after the other headers,
	include gdk-pixbuf-aliasdef.c at the bottom.
