* argp/argp-fmtstream.h: Likewise.
* argp/argp-help.c: Likewise.
* 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.

* 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.

1997-04-08 07:19 H.J. Lu <hjl@gnu.ai.mit.edu>
* 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>.

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

symbols which violate the name space rules. gcc defines symbols
for the architecture which are not protected by an underscore
character.

value to long long int.
* sysdeps/libm-i387/s_rinttoll.S: New file.
* sysdeps/libm-ieee754/s_rintl.c: Many corrections. The previous
version was full of errors.

`double'.
(rinttoll): Likewise.

if not already defined.
1997-04-05 16:14 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/unix/sysv/linux/netatalk/at.h: Include <sys/socket.h> to
get definition of sa_family_t for <linux/atalk.h>.
Reported by a sun <asun@zoology.washington.edu>.
