Update.
1998-04-07 16:18 Ulrich Drepper <drepper@cygnus.com> * libc.map: Add __asprintf to GLIBC_2.1. * elf/dlerror.c: Use __asprintf, not asprintf. * libio/stdio.h: Declare __asprintf. * stdio-common/asprintf.c: Define as __asprintf and make asprintf a weak alias. * elf/dl-minimal.c: Add definition of strtol and strtoul (und friends) to avoid inclusion from libc_pic.a. * elf/dl-runtime.c: Undo last patch. * stdlib/strtod.c: Don't use mbtowc, use btowc. * sysdeps/i386/dl-machine.h (dl_platform_init): Don't use "i386" as default, use NULL.
