	* app/Makefile.am
	* plug-ins/script-fu/Makefile.am: put the regex and MMX sources to
	EXTRA_DIST so they get distributed unconditionally.

	* tools/pdbgen/pdb/layer.pdb: re-enabled the layer_mask procs but
	let them use accessors (which don't exist)...

	* app/pdb/pdb_glue.h: ... #define the accessors as macros here.

	Yes, this is ugly, but I simply don't fully understand pdbgen
	yoshcode.

	* app/pdb/internal_procs.c
	* app/pdb/layer_cmds.c
	* libgimp/gimplayer_pdb.[ch]: regenerated with the layer_mask
	accessors.

	* app/tools/Makefile.am: add the files which are not built to
	EXTRA_DIST.

	* pixmaps/Makefile.am
	* pixmaps/channel.xbm
	* pixmaps/eye.xbm
	* pixmaps/layer.xbm
	* pixmaps/linked.xbm
	* pixmaps/mask.xbm: removed.

	* plug-ins/Makefile.am: build XJT again because the layer_mask
	stuff is back. Perl also seems to build again.

	* plug-ins/common/aa.c: explicit casting fixes some warnings.

	* plug-ins/script-fu/interp_regex.c: #include "config.h".
