Update.

2001-04-19  Alan Modra  <amodra@one.net.au>

	* Makerules (libc_pic.os): Add $(LDFLAGS-c_pic.os).
	* sysdeps/hppa/Makefile (LDFLAGS-c_pic.os): Define.
	(CFLAGS-.os): Remove.

	* sysdeps/unix/sysv/linux/hppa/sysdep.h (CALL_MCOUNT): Update comment.

	* sysdeps/unix/sysv/linux/hppa/sys/ucontext.h (NGREG, NFPREG,
	gregset): Correct for new kernel definitions.

2001-04-19  Alan Modra  <alan@linuxcare.com.au>

	* sysdeps/hppa/elf/initfini.c: Change dlt reg save to r3 and
	generate unwind info by hand.

2001-04-19  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/powerpc/mmap64.c (__mmap64): Optimize a bit.

	* configure.in: Correct regular expression for msgfmt.
	Patch by Bruno Haible <haible@ilog.fr>.
