	* elf/dl-minimal.c: Add definition of calloc.
	* elf/version.c: Add casts to prevent warnings.
	(_dl_check_map_versions): Use calloc instead of malloc+memset.

	* 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>.

	* math/libm-test.c (check_long): New function.
	(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.

	* stdlib/erand48_r.c (erand48_r): Build double value using
	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.

	* libio/genops.c (_IO_flush_all_linebuffered): don't flush on
	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.
	Patch by Marcus G. Daniels <marcus@cathcart.sysc.pdx.edu>.

1997-04-07 15:34  Ulrich Drepper  <drepper@cygnus.com>

	indicator of streams.
	* stdio-common/tst-ferror.input: New file.

	* isomac.c: Let tests not fail because the compiler defines itself

	value to long long int.
	* sysdeps/libm-i387/s_rinttoll.S: New file.

	* sysdeps/libm-ieee754/s_rintl.c: Many corrections.  The previous
