dwarf2-signal.h (SIGNAL_HANDLER): Name siginfo_t pointer arg.

2002-04-19  David S. Miller  <davem@redhat.com>

	* include/dwarf2-signal.h (SIGNAL_HANDLER): Name siginfo_t pointer
	arg.
	(MAKE_THROW_FRAME): Define for 32-bit and 64-bit sparc.
	(INIT_SEGV, INIT_FPE): Use direct __libc_sigaction installation
	on Sparc too.
	* include/sparc-signal.h (FLUSH_REGISTER_WINDOWS): Define properly
	for 64-bit sparc.
	(MAKE_THROW_FRAME): Use long for sp/retaddr so 64-bit works.
	* sysdeps/sparc/locks.h: New file.
	* configure.in (SIGNAL_HANDLER): Set to include/sparc-signal.h
	on all sparc Solaris configurations.  Set to
	include/dwarf2-signal.h on sparc Linux.
	* configure: Regenerate
	* configure.host (can_unwind_signal): sparc*-linux* can do it now.
