glibc/sysdeps/unix/sysv/linux/xstatconv.c
Ulrich Drepper 0f6b172f72 Update.
2000-08-17  Ulrich Drepper  <drepper@redhat.com>

	* stdio-common/printf_fp.c: Fix chars_needed computation.
	Patch by Greg McGary <greg@mcgary.org>.

2000-08-17  Jakub Jelinek  <jakub@redhat.com>

	* elf/dl-load.c (_dl_map_object): Don't crash if both loader and
	_dl_loaded are NULL.

2000-08-17  Jakub Jelinek  <jakub@redhat.com>

	* manual/arith.texi (feholdexcept): Returns 0 on success.

2000-08-17  Andreas Jaeger  <aj@suse.de>

	* sysdeps/gnu/net/if.h (struct ifreq): Add ifru_newname.
	(ifr_newname): New.
	Reported by Andi Kleen <ak@suse.de>.

2000-08-17  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/alpha/fpu/fedisblxcpt.c: New file.
	* sysdeps/alpha/fpu/feenablxcpt.c: New file.
	* sysdeps/alpha/fpu/fegetexcept.c: New file.

2000-08-16  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/xstatconv.c (xstat32_conv): Test sizes
	of buf->st_ino and kbuf->st_ino, not __st_ino.
	If _HAVE_STAT64___ST_INO is not defined, don't use __st_ino at all.
	* sysdeps/unix/sysv/linux/getdents64.c: Change path in #include
	directive so that only linux/getdents.c is used, not some
	architecture specific one.

2000-08-16  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/i386/fpu/fegetexcept.c (fegetexcept): Return currently
	enabled, not disabled exceptions.
	* sysdeps/i386/fpu/fedisblxcpt.c (fedisableexcept): Likewise.
	* sysdeps/i386/fpu/feenablxcpt.c (feenableexcept): Likewise.

	($(addprefix $(objpfx),$(tests)),
	$(addprefix $(objpfx),$(librt-tests))):
	* include/link.h: Undo last patches.  Hurd now has stat64.
