[BZ #6860]
* hurd/hurd/signal.h (HURD_MSGPORT_RPC): Fix a typo.
2008-07-18 Daniel Jacobowitz <dan@codesourcery.com>
* Makefile (check-data): Check data directory in add-ons.
* elf/Makefile (check-data): Likewise.
2008-08-18 Roland McGrath <roland@redhat.com>
* configure.in (--with-cpu): Check compiler support for -march/-mcpu.
* configure: Regenerated.
* config.make.in (cflags-cpu): New substituted variable.
(with-cpu): Variable removed.
* Makeconfig (+cflags): Use $(cflags-cpu), not $(with-cpu).
2008-08-14 Ryan S. Arnold <rsa@us.ibm.com>
[BZ #6845]
* sysdeps/powerpc/fpu/bits/mathinline.h (__signbitl): Copy new
__signbitl definition and __LONG_DOUBLE_128__ guard from:
* sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h: Remove as
redundant. Functions which call floating point assembler operations
should go into a sysdeps powerpc/fpu directory.
2008-08-15 Ulrich Drepper <drepper@redhat.com>
* sysdeps/unix/sysv/linux/x86_64/bits/mman.h: Define MAP_STACK.

2008-08-14 Ulrich Drepper <drepper@redhat.com>
* sysdeps/x86_64/memset.S: Reduce size of tables for PIC.
* sysdeps/unix/sysv/linux/dl-origin.c (_dl_get_origin): Undo all
change related to AT_EXECFN. We cannot use that string.
* sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Remove
_dl_execfn member.

2008-08-13 Ulrich Drepper <drepper@redhat.com>
[BZ #6544]
* libio/fmemopen.c: Implement binary mode. In this mode no NUL
byte gets added to writes and seeks from the end use the length of
the buffer and not the currently terminating NUL byte.
[BZ #6634]
* login/utmp_file.c (getutent_r_file): Take additional parameter.
Set to true if locking failed.
(getutid_r_file): Adjust caller.
(pututline_file): Likewise. Return NULL in this case.
Patch mostly by halesh.s@gmail.com.
2008-08-12 Ulrich Drepper <drepper@redhat.com>

* sysdeps/unix/sysv/linux/ifaddrs.c (struct sockaddr_ll_max):
Define.
(struct ifaddrs_storage): Use it instead of sockaddr_ll.
2008-08-12 Ryan S. Arnold <rsa@us.ibm.com>
[BZ #6839]
* sysdeps/powerpc/powerpc32/dl-machine.c (CHECK_STATIC_TLS): Remove
macro since it is now available in elf/dynamic-link.h.
2008-08-12 Roland McGrath <roland@frob.com>
* hurd/hurd/signal.h (HURD_MSGPORT_RPC): Avoid -Wparenthesis triggers,
in case used outside of libc.
Reported by Samuel Thibault <samuel.thibault@ens-lyon.org>
2008-08-11 Ulrich Drepper <drepper@redhat.com>
* resolv/res_mkquery.c (res_nmkquery): Call ns_name_compress

capability and ISA 2.06.

macro to detect use of 128 bit long double.
Patch by Ryan S. Arnold <rsa@us.ibm.com>.

* Implement "e" option for popen to open file descriptor with the
close-on-exec flag set. Implemented by Ulrich Drepper.
* Implement "b" mode for fmemopen. In this mode writes writes don't
implicitly add a NUL byte and seeks from the end of the buffer really
use the buffer end, not the string length as the basis.
Implemented by Ulrich Drepper.
* Many functions, exported and internal, now atomically set the close-on-exec
flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
