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.
