Don't define reentrant hsearch functions uless __USE_GNU. * nss/nsswitch.c: Pretty print. * sunrpc/clnt_udp.c (clntudp_call): Initialize outlen to prevent warning. * sysdeps/unix/i386/sysdep.h (DO_CALL): Use lcall, binutils have been fixed meanwhile. Reported by Zack Weinberg <zack@rabi.phys.columbia.edu>. 1997-07-24 00:53 Philip Blundell <Philip.Blundell@pobox.com> * db/hash/hash.c (init_hash): Only use statbuf.st_blksize if it exists for this port. 1997-07-24 00:12 Philip Blundell <Philip.Blundell@pobox.com> * sysdeps/standalone/arm/bits/errno.h (ESTALE): Add. 1997-07-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/argp.texi (Argp Option Vectors): Use @minus, not @math, to format a proper minus sign. 1997-07-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/fraiseexcpt.c: Don't handle FE_INEXACT specially, the standard doesn't require it. * math/test-fenv.c (test_exceptions): Add IGNORE_INEXACT argument, if non-zero then don't test inexact flag. Callers changed. (set_single_exc): Ignore inexact flag if underflow or overflow exception is raised. 1997-07-23 05:10 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sys/fsuid.h: New file.

Lu <hjl@gnu.ai.mit.edu> * inet/netinet/in.h (htons): Fix typos. * sysdeps/i386/bits/htontoh.h (__ntohs): Return the value. 1997-07-22 11:47 Ulrich Drepper <drepper@cygnus.com> * nss/nsswitch.c (nss_lookup_function): Include function.def, not functions.def.
