Mon Aug 9 12:48:04 2004 Matthias Clasen <maclas@gmx.de> Add hidden aliases for exported symbols which are used internally in order to get rid of many PLT entries. (#145519, Arjan van de Ven) * gtk/Makefile.am: Add rules to generate gtk.def and from gtk.symbols, and make make check check the abi with abicheck.sh. (gtk_private_h_sources): Add gtkinternals.h (gtk_built_private_headers): Add gtkalias.h (gtk_extra_sources): Add gtk.symbols (EXTRA_DIST): Add makegtkalias.pl and abicheck.sh * gtk/gtk.symbols: New file. Definition of the GTK+ ABI. The file can be processed by cpp to filter out certain subsets of symbols. * gtk/abicheck.sh: New file. Script to check the actually symbols exported from libgtk-x11.2.0.so against the symbols found in gtk.symbols. * gtk/makegtkalias.pl: New file. Perl script to generate the header containing the alias definitions for internally used exported symbols from a list of symbols. * gtk/gtkinternals.h: New file. An uninstalled header listing symbols which must be exported for some reason and do not appear in any other header. * gtk/*.c: Include gtkalias.h
