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

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

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

	* 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.

	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.

	* math/math.h (rinttol): Argument is of type `long double' not
	`double'.
	(rinttoll): Likewise.
	(roundtol): Likewise.
	(roundtoll): Likewise.

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.
