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).
