2005-03-20 Matthias Clasen <mclasen@redhat.com> Make PLT-reduction work with gcc4, and don't include everything in gdkalias.h: * gtk/grk.symbols: Group symbols by header and source file. * gtk/makegtkalias.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 makegtkalias.pl -def * gdk/Makefile.am (gtkaliasdef.c): Add a rule to generate this file. * gtk/*.c: Include gtkalias.h after the other headers, include gtkaliasdef.c at the bottom. * gtk/*.h: Small cleanups.
