Tue Aug 10 23:53:59 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_pixbuf.def and gdk-pixbuf-alias.h from gdk-pixbuf.symbols, and make make check check the abi with abicheck.sh. * gdk/gdk-pixbuf.symbols: New file. Definition of the gdk-pixbuf 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_pibuf.2.0.so against the symbols found in gdk-pixbuf.symbols. * gdk/makegdkpixbufalias.pl: New file. Perl script to generate the header containing the alias definitions for internally used exported symbols from a list of symbols. * *.c: Include gdk-pixbuf-alias.h
