Matthias Clasen 0742ff3ae3 Add hidden aliases for exported symbols which are used internally in order
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
