Add hidden aliases for exported symbols which are used internally in order

Browse Source 
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
