[PATCH] Assorted SPARC fixes


Hi!

The first 2 changed files fix most of the cancellation tests on sparc64
(the only remaining failures ATM are:
tst-cancel24 (failes due to buggy G++ 3.4.x, I have verified it is fixed
in 4.1.x), tst-cancelx{4,5} (cancellation for pause failed, no idea what's
going up yet) and tst-cancelx21 (haven't looked)), most of the changes
are to use sparc64 stat64/lstat64 syscalls (not fstat64 yet, since it is
broken in the kernel) to get nsec precision in *stat* and the last 3
changed files is c++ types check data addition and while I've been doing
that I have also updated alpha.

2006-01-09  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/sparc/bits/setjmp.h (_JMPBUF_UNWINDS): Add
	stack bias to mc_fp field.

	* sysdeps/unix/sysv/linux/sparc/sparc64/kernel_stat.h
	(struct kernel_stat): Rename st_[amc]time fields to st_[amc]time_sec.
	(struct kernel_stat64): New type.
	(_HAVE___UNUSED1, _HAVE___UNUSED2, _HAVE_STAT___UNUSED1,
	_HAVE_STAT___UNUSED2, _HAVE_STAT___UNUSED3, _HAVE_STAT___UNUSED4,

	_HAVE_STAT64___UNUSED3, _HAVE_STAT64___UNUSED4,
	_HAVE_STAT64___UNUSED5, _HAVE_STAT64___PAD1, _HAVE_STAT64___PAD2):
	Remove.

	for 32-bit code.
	* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_TRUNCATE64_SYSCALL,
	__ASSUME_MMAP2_SYSCALL) Don't define for sparc64.
	(__ASSUME_STAT64_SYSCALL): Only define for sparc64 for >= 2.6.12 kernels.
