	* sunrpc/clnt_udp.c (clntudp_call): Initialize outlen to prevent
	warning.

	* sysdeps/unix/i386/sysdep.h (DO_CALL): Use lcall, binutils have

	* 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.
	Provided by Michael Deutschmann <ldeutsch@mail.netshop.net>.
	* sysdeps/unix/sysv/linux/Makefile (headers): Add sys/fsuid.h.
	* sysdeps/unix/sysv/linux/Dist: Add sys/fsuid.h.

1997-07-16 10:09  Fila Kolodny  <fila@ibi.com>

	* resolv/gethnamaddr.c: Define MAXHOSTNAMELEN as 256, since RFC 1034
	and 1035 state that a fully qualified domain name cannot exceed 255
	octets in length.
	* resolv/nss_dns/dns-host.c: Likewise.

1997-07-22 09:54  H.J. 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.
	Patch by Klaus Espenlaub <kespenla@hydra.informatik.uni-ulm.de>.
