	* locale/setlocale.c (_nl_current): Add element with index LC_ALL.
	Reported by Greg McGary <gkm@eng.ascend.com>.

	* manual/libc.texinfo: Update malloc documentation for new malloc.
	* manual/memory.texi: Likewise.
	Patch by Wolfram Gloger <wmglo@dent.med.uni-muenchen.de>.

	(check_longlong): New function.
	(rinttol_test): New function.
	(rinttoll_test): New function.

	* nis/nss_compat/compat-grp.c (in_blacklist): Improve a bit.
	* nis/nss_compat/compat-pwd.c: Likewise.
	* nis/nss_compat/compat-spwd.c: Likewise.

	ieee754_double union and use random bits in different order to
	increase effect of seed.
	Reported by David Mosberger-Tang <davidm@AZStarNet.com>.

	* sunrpc/svc_auth.c: Moved to ...
	* sysdeps/generic/svc_auth.c: ...here.

	a read-only stream.

1997-04-09 01:19  Ulrich Drepper  <drepper@cygnus.com>

	* malloc/malloc.c (mALLOC_STATs) [MALLOC_DEBUG>1]: Put declaration
	in correct place.
