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>.
