* sysdeps/unix/sysv/Dist: Add direct.h.
* sysdeps/unix/sysv/linux/Dist: Add netinet/tcp.h.
* Make-dist ($(tardir).tar): Prefer writing temporary file to
$TMPDIR is available. The default is /tmp.
* sysdeps/generic/ip.h: Move to...
* sysdeps/generic/netinet/ip.h: ...here.
* Makefile (tests): Quote $(CC) argument to isomac program.
Patch by H.J. Lu <hjl@gnu.ai.mit.edu>.
* sysdeps/i386/setjmp.S (__setjmp): Fix fatal bug where 0 argument
is placed in wrong place on the stack.
Reported by Marc Lehmann <mlehmann@hildesheim.sgh-net.de>.
* sysdeps/tst-setjmp.c: Add new test for above problem.
* sysdeps/libm-i387/e_pow.S: Compute PIC addres early.

* sysdeps/libm-i387/e_powl.S: Likewise.
1997-03-18 23:18 Ulrich Drepper <drepper@cygnus.com>
* time/offtime.c (__offtime): Change type of `yg' to long int.
Reported by a sun <asun@zoology.washington.edu>.
1997-03-18 23:08 a sun <asun@zoology.washington.edu>
* sysdeps/unix/sysv/linux/net/if_ppp.h (PPP_VERSION): Define to
2.2.0 to prevent version mismatch.
1997-03-17 19:26 Andreas Jaeger <aj@arthur.pfalz.de>
* stdio-common/printf_fphex.c (MIN): Only define MIN if not
already defined.
1997-03-14 23:34 Geoff Keating <geoffk@ozemail.com.au>
* sysdeps/unix/sysv/linux/powerpc/termbits.h: Leave ioctl numbers
in ioctls.h.
* elf/rtld.c (_dl_start): Call elf_machine_runtime_setup when the
loader first relocates itself.
* sysdeps/powerpc/elf/start.c (__start1): Fix bug for static objects.
* sysdeps/powerpc/dl-machine.h (elf_machine_rela): Fix bugs in
jump slot relocation. Prefer relative branches (some PowerPC chips
don't predict absolute branches).
(elf_machine_runtime_setup): Simplify and correct expressions.
(RTLD_START): Fix bug changing _dl_starting_up.
* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Added. Deal with
strange Linux/PPC padding of initial stack.
1997-03-11 04:14 Geoff Keating <geoffk@ozemail.com.au>
* sysdeps/unix/sysv/linux/powerpc/termbits.h: Increase NCCS to 39,
for future expansion.

can't have a switch statement.
* sysdeps/powerpc/elf/start.c (__start1): Explain why it can't be
static.
* sysdeps/powerpc/elf/start.c (_start): Use .previous to avoid
confusing gcc's idea of the current section.

RTLD_START): Likewise.
1997-03-08 09:10 Geoff Keating <geoffk@ozemail.com.au>
* sysdeps/powerpc/dl-machine.h (elf_machine_rela,
elf_machine_runtime_setup): Flush data & instruction caches when
necessary, for 603/604 support. Add better support for large PLTs.
(elf_machine_rela): Remove relocations that wouldn't work if
anyone ever used them. Use memcpy for copy reloc, it'll be safe.
Never target branch relocations at a PLT entry.
* sysdeps/powerpc/bsd-setjmp.S: Make jump to PLT entry if we are
generating PIC.
* sysdeps/powerpc/bsd-_setjmp.S: Likewise.
* sysdeps/powerpc/setjmp.S: Likewise.

error.
1997-03-17 19:00 Philip Blundell <phil@london.uk.eu.org>
* nss/nss_files/files-service.c (servbyname): Match any protocol
