Update.

1998-03-18  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* manual/memory.texi (Heap Consistency Checking): Document
	MALLOC_CHECK_.  Based on a text by Wolfram Gloger.

1998-03-18 17:11  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* manual/Makefile: Add missing rules.

1998-03-18  Ulrich Drepper  <drepper@cygnus.com>

	* timezone/Makefile (generated): Define to remove all stamp files.

	* sysdeps/generic/strsep.c: Also undefine __strsep.

	* string/strdup.c: Undefine __strdup and strdup first.
	* string/strndup.c: Likewise.

	* string/bits/string2.h: Correct strtok_r and strsep.
	Add strndup optimization.

	* sysdeps/generic/strsep.c: Little optimization.
