(_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. * sysdeps/i386/Makefile (CFLAGS-initfini.s): Use $(cc-mtune).
