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

2005-03-13  Matthias Clasen  <mclasen@redhat.com>

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

	* glib/glib.symbols: Group symbols by header and source file.
	* glib/makegalias.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 makegalias.pl -def
	* glib/Makefile.am (galiasdef.c): Add a rule to generate this
	file.
	* glib/*.c: Include galias.h after the other GLib headers,
	include galiasdef.c at the bottom.
