Update.

2000-03-24  Andreas Jaeger  <aj@suse.de>

	* Makefile (postclean): Added soversions.i.

2000-03-24  Scott Bambrough  <scottb@netwinder.org>

	* sysdeps/arm/fpu/fpu_control.h: Define _FPU_MASK_IM, _FPU_MASK_ZM,
	_FPU_MASK_OM, _FPU_MASK_UM, _FPU_MASK_PM, _FPU_MASK_DM, _FPU_DEFAULT,
	and _FPU_IEEE.  Change _FPU_RESERVED.

2000-03-24  Scott Bambrough  <scottb@netwinder.org>

	* sysdeps/unix/sysv/linux/arm/sys/ucontext.h: New file.

2000-03-24  Roland McGrath  <roland@baalperazim.frob.com>

	* sysdeps/posix/getaddrinfo.c: Include <net/if.h> for if_nametoindex.
	(gaih_inet): Remove unused duplicate variable.

	* inet/getnameinfo.c (getnameinfo): Use IFNAMSIZ, not MAXHOSTNAMELEN.
	Don't use __libc_sa_len, which only exists for Linux.  Just handle
	AF_INET and AF_INET6 directly as well as AF_LOCAL, since those are the
	only flavors supported by this function anyway.

2000-03-24  Geoff Clare  <gwc@unisoft.com>

	* stdlib/strfmon.c: corrected problems with missing signs and
	missing or extra spaces; allow for sign strings longer than
	one character; add padding to ensure positive and negative
	formats are aligned when a left precision is used.

2000-03-26  Ulrich Drepper  <drepper@redhat.com>

	* stdlib/random_r.c (__setstate_r): Allow RNGs of type 4.
	Patch by John Mizel <John.Mizel@msdw.com>.
