	Reported by Greg McGary <gkm@eng.ascend.com>.

	* manual/libc.texinfo: Update malloc documentation for new malloc.
	* manual/memory.texi: Likewise.

	indicator of streams.

	* isomac.c: Let tests not fail because the compiler defines itself
	symbols which violate the name space rules.  gcc defines symbols
	for the architecture which are not protected by an underscore
	character.

1997-04-06 00:42  Ulrich Drepper  <drepper@cygnus.com>

	* misc/tst-tsearch.c: Include <string.h>.  Define _GNU_SOURCE only
	if not already defined.
