Mon Aug 9 15:41:17 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) * gdk/Makefile.am: Add rules to generate gdk.def and gdkalias.h from gdk.symbols, and make make check check the abi with abicheck.sh. * gdk/gdk.symbols: New file. Definition of the GDK ABI. The file can be processed by cpp to filter out certain subsets of symbols. * gdk/abicheck.sh: New file. Script to check the actually symbols exported from libgdk-x11.2.0.so against the symbols found in gdk.symbols. * gdk/makegdkalias.pl: New file. Perl script to generate the header containing the alias definitions for internally used exported symbols from a list of symbols. * gdk/*.c, gdk/x11/*.c: Include gdkalias.h
