+ * 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.
+
1998-04-04 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* resolv/Makefile: Include ../Makeconfig - needed for building
