Matthias Clasen 3448a27829 Make work again.
2005-03-14  Matthias Clasen  <mclasen@redhat.com>

	* abicheck.sh: Make work again.

	* gsourceclosure.c: Fix a typo.

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

	* gobject.symbols: Group symbols by header and source
	file.
	* makegobjectalias.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
	* Makefile.am (gobjectaliasdef.c): Add a rule to
	build this file.
	* *.c: Include gobjectalias.h after the other i
        GLib headers, include gobjectaliasdef.c at the bottom.
