Update.
1998-08-25 11:43 Ulrich Drepper <drepper@cygnus.com> * elf/elf.h: Add syminfo stuff and other DT_* from Solaris' ELF. 1998-08-25 Bernd Schmidt <crux@Pool.Informatik.RWTH-Aachen.DE> * argp/argp.h: Use __inline__ not inline. * sysdeps/i386/bits/select.h (FD_ZERO): Rewrite asm not to indicate an input register as being clobbered. * sysdeps/i386/memset.c (memset): Likewise. * sysdeps/i386/bzero.c (__bzero): Likewise. * sysdeps/i386/memcopy.h ({BYTE,WORD}_COPY_[FB]WD): Likewise. 1998-08-25 Andreas Jaeger <aj@arthur.rhein-neckar.de> * stdlib/jrand48_r.c (__jrand48_r): Set also upper half of result. Fixes PR libc/757 (Reported by Michael Creutz <creutz@bnl.gov).
