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>.
