Update.
* time/strftime.c (my_strftime): Delay use of *tp values until latest possible point to allow partly initialized structures (e.g., from strptime). * sysdeps/unix/sysv/linux/init-first.c [!PIC]: Define __libc_init_first using init-first.h. 1998-04-30 18:20 H.J. Lu <hjl@gnu.org> * elf/dl-load.c (_dl_init_paths): Don't check the dynamic loader if PIC is not defined. 1998-09-11 Ulrich Drepper <drepper@cygnus.com>
