	* sysdeps/powerpc/dl-machine.h: Fix typo in last change.

	* sysdeps/unix/sparc/sysdep.h: Update copyright.

1997-03-19 15:13  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* linuxthreads/sysdeps/sparc/pt-machine (RELEASE): Fix.

	* stdlib/tst-strtol.c: Save the value of errno, printf may modify
	it.

	* sysdeps/sparc/DEFS.h [HAVE_ELF]: Use type @function in the FUNC
	macro on ELF systems.

	* sysdeps/sparc/configure.in: Fix.

	* sysdeps/sparc/dl-machine.h: Fix OPCODE_CALL.
	* sysdeps/sparc/setjmp.S: Fix my bugs.

	* sysdeps/unix/sysv/linux/sparc/Dist: Add start.c, fork.S, and pipe.S.
	* sysdeps/unix/sysv/linux/sparc/Makefile: Define asm-CPPFLAGS and
	as-FLAGS-.so.
	* sysdeps/unix/sysv/linux/sparc/syscalls.list: Add fork, pipe, and
	syscall.
	* sysdeps/unix/sysv/linux/sparc/fork.S: New file.
	* sysdeps/unix/sysv/linux/sparc/pipe.S: New file.
	* sysdeps/unix/sysv/linux/sparc/socket.S: Fix.
	* sysdeps/unix/sysv/linux/sparc/sysdep.h: Fix.

	* elf/dl-lookup.c (do_lookup): Return true if we found a weak
	symbol.
	(_dl_lookup_symbol): Test against the symbol being global not
	against the symbol being not weak (fixes important problem with
	the SPARC linker)

	* sysdeps/unix/sysv/linux/sparc/brk.c: Fix.

	* sysdeps/unix/sysv/linux/sparc/start.c: Startup code for
	Linux/SPARC (while I get my asmCPPFLAGS-so variable).

1997-03-20 01:49  Ulrich Drepper  <drepper@cygnus.com>
	* sysdeps/libm-ieee754/s_tanhl.c (__tanhl): Correct handling of -inf.
	* elf/dl-reloc.c (RESOLVE): Don't try to resolve local symbols.
