[BZ #3252, BZ #3253]cvs/fedora-glibc-20060925T1535

2006-09-25  Jakub Jelinek  <jakub@redhat.com>
	[BZ #3252]
	* sysdeps/unix/sysv/linux/powerpc/fchownat.c (fchownat): Handle only
	fchownat syscall and __ASSUME_LCHOWN_SYSCALL case inline, call
	__{,l}chown to handle the rest.
	* sysdeps/unix/sysv/linux/i386/fchownat.c (fchownat): Handle only
	fchownat syscall and __ASSUME_32BITUIDS case inline, call
	__{,l}chown to handle the rest.
	* sysdeps/unix/sysv/linux/sparc/sparc32/fchownat.c: Include
	i386/fchownat.c.
	* sysdeps/unix/sysv/linux/s390/s390-32/fchownat.c: Likewise.
	* sysdeps/unix/sysv/linux/sh/fchownat.c: Likewise.

	[BZ #3253]
	* posix/glob.c (glob_in_dir): Don't alloca one struct globlink at a
	time, rather allocate increasingly bigger arrays of pointers, if
	possible with alloca, if too large with malloc.

2006-09-24  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/fpu/libm-test-ulps: Updated.

	* sysdeps/ieee754/ldbl-128/s_lrintl.c (__lrintl): Fix 2 typos.
