1998-11-17  Ulrich Drepper  <drepper@cygnus.com>

	* stdio-common/printf_fphex.c (__printf_fphex): Correct printing
	of denormalized numbers.

1998-10-06  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/dl-machine.h (elf_machine_load_address): Suppress
	another parentheses warning, make nano-optimisation.

	* sysdeps/powerpc/dl-machine.h (_dl_runtime_resolve): Preserve
	saved LR on stack so _mcount works.
	(_dl_prof_resolve): Likewise.
	* sysdeps/powerpc/register-dump.h: Print FPRs.  Adjust for correct
	signal handler calling convention.
	* sysdeps/unix/sysv/linux/powerpc/sigcontextinfo.h: Adjust for
	correct signal handler calling convention---more like x86 linux and
	mklinux, less like linux-ppc versions between 2.1 and 2.1.126.

1998-11-17  Ulrich Drepper  <drepper@cygnus.com>

	* configure.in: Correct allowed makeinfo version.

1998-11-17  Philip Blundell  <pb@nexus.co.uk>

	* sysdeps/generic/bits/mathdef.h: Fix typo.

	* intl/locale.alias: Change `japanese' alias to match X11R6's.
