* elf/dl-debug.c (_dl_debug_initialize): Check r->r_map for 0

rather than r->r_brk.

	* elf/dl-load.c (decompose_rpath): Return bool rather than void.
	If l->l_name is on inhibit_rpath list, set sps->dirs to -1 and
	return false, otherwise return true.
	(cache_rpath): Return decompose_rpath return value.

2006-11-07  Jakub Jelinek  <jakub@redhat.com>

	* include/libc-symbols.h (declare_symbol): Rename to...
	(declare_symbol_alias): ... this.  Add ORIGINAL argument, imply
	strong_alias (ORIGINAL, SYMBOL) in asm to make sure it preceedes
	.size directive.
	* sysdeps/gnu/errlist-compat.awk: Adjust for declare_symbol_alias
	changes.
	* sysdeps/gnu/siglist.c: Likewise.
