Update.

2000-09-28  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

	* sysdeps/unix/sysv/linux/kernel-features.h: Add __ASSUME_IPC64, only
	define it for powerpc for kernel >= 2.4.0.
	* sysdeps/unix/sysv/linux/msgctl.c: Test for __ASSUME_IPC64, not
	__ASSUME_32BITUIDS.
	* sysdeps/unix/sysv/linux/semctl.c: Likewise.
	* sysdeps/unix/sysv/linux/shmctl.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/bits/ipc.h: Sync with kernel.
	* sysdeps/unix/sysv/linux/powerpc/bits/msq.h: New file.
	* sysdeps/unix/sysv/linux/powerpc/bits/sem.h: New file.
	* sysdeps/unix/sysv/linux/powerpc/bits/shm.h: New file.

2000-09-28  Martin Schwidefsksy    <schwidefsky@de.ibm.com>

	* sysdeps/s390/atomicity.h: Fix compare_and_swap.
	* sysdeps/unix/sysv/linux/s390/bits/fcntl.h
	(F_GETLK64,F_SETLK64,F_SETLKW64): Use values from 2.4.0-test8.

2000-09-28  Denis Joseph Barrow     <djbarrow@de.ibm.com>

	* sysdeps/unix/sysv/linux/s390/sys/procfs.h: Use definitions from
	ucontext.h.
	* sysdeps/unix/sysv/linux/s390/sys/ucontext.h: Fix ucontext structure.

2000-09-27  Andreas Schwab  <schwab@suse.de>

	* math/Makefile (distribute): Explicitly add the long double test
	sources, to get them included even if long double is not supported.

2000-09-27  Jes Sorensen  <jes@linuxcare.com>

	* elf/soinit.c (struct object): Move definition to gccframe.h and
	include it.  Problem identified by HJ Lu.

	* sysdeps/ia64/gccframe.h: New file.  ia64 specific version of
	struct object to be searched for frame unwind info.
	* sysdeps/generic/gccframe.h: New file.  Generic version of
	struct object to be searched for frame unwind info.

2000-09-28  Ulrich Drepper  <drepper@redhat.com>

	* manual/errno.texi: Correct error text for ENXIO.
	Reported by Jörg Schilling <schilling@fokus.gmd.de>.

2000-09-27  Jes Sorensen  <jes@linuxcare.com>

	* sysdeps/ia64/fpu/fsetexcptflg.c (fesetexceptflag): Set the
	exception status bits rather than the exception disable bits.
	Don't include math.h.

	* sysdeps/ia64/fpu/fgetexcptflg.c (fegetexceptflag): Report the
	status of exceptions currently raised rather than which exceptions
	are enabled.

	* sysdeps/ia64/fpu/fclrexcpt.c (feclearexcept): Typecase to fenv_t
	rather than unsigned long int.

	* sysdeps/ia64/fpu/fedisblxcpt.c (fedisableexcept): Only disable
	the exceptions actually requested by the caller and not just
	disable all exceptions.

	* sysdeps/ia64/fpu/feenablxcpt.c (feenableexcept): Exceptions on
	the ia64 are enabled by clearing the respective bits in the fpsr,
	not setting them.

	* sysdeps/ia64/bits/fenv.h: typedef fexcept_t and fenv_t to
	unsigned long int rather than unsigned long to be consistent with
	the coding conventions.

2000-09-20  H.J. Lu  <hjl@gnu.org>

	* sysdeps/ia64/fpu/fesetenv.c (fesetenv): Use fenv_t instead of
	unsigned long int.
	* sysdeps/ia64/fpu/fesetround.c (fesetround): Likewise.

2000-09-28  Ulrich Drepper  <drepper@redhat.com>

	* string/bits/string2.h: Unify #if usage.

2000-09-27  Jakub Jelinek  <jakub@redhat.com>

	* math/test-fenv.c (feexcp_mask_test): If enabling all exceptions
	and disabling underflow or overflow, disable inexact as well.

	* sysdeps/gnu/netinet/tcp.h: Add tcp_info defines and types.
