Roland McGrath 2103c260f9 * sysdeps/generic/ldsodefs.h (_dl_out_of_memory_internal): Remove decl.
(_dl_out_of_memory): Use rtld_hidden_proto.
	* elf/dl-error.c (_dl_out_of_memory): Use rtld_hidden_data_def.
	(_dl_signal_error): Don't use INTUSE on _dl_out_of_memory.
	* elf/dl-open.c (_dl_open): Likewise.
	* elf/dl-deps.c (_dl_map_object_deps): Likewise.

	* sunrpc/des_impl.c (des_set_key): Make first argument unsigned char *.

	* elf/dl-addr.c (_dl_addr): Add a cast.

	* elf/unload3mod4.c: Declare foo.
	* elf/testobj2.c: Include <stdio.h>.

	* sysdeps/gnu/errlist.awk: Emit NERR macro for _sys_nerr_internal
	value constant, and use it in the defn.
	* sysdeps/gnu/errlist-compat.awk: Use NERR in array decl.
	Use actual size for compat array decls.

	* config.make.in (cc-mtune): New substituted variable.
	* configure.in (libc_cv_cc_mtune): New test for -mtune= switch,
	done only if libc_mtune_example is defined.
	* configure: Regenerated.
	* sysdeps/i386/configure.in (libc_mtune_example): Set it.
	* sysdeps/i386/configure: Regenerated.
