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>.
