OK, so the list of macros that should be marked obsolete is: - AC_FUNC_ERROR_AT_LINE - AC_FUNC_GETLOADAVG (already marked obsolescent) - AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK - AC_FUNC_MEMCMP (already marked obsolescent) - AC_FUNC_MKTIME - AC_FUNC_STAT, AC_FUNC_LSTAT (already marked obsolescent) - AC_FUNC_STRTOD - AC_REPLACE_FNMATCH (already marked obsolescent) Removing those that are already marked obsolescent, the following remain: - AC_FUNC_ERROR_AT_LINE - AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK - AC_FUNC_MKTIME - AC_FUNC_STRTOD Here is a proposed patch. 2010-08-28 Bruno Haible <br...@clisp.org> * doc/autoconf.texi (Particular Functions): Mark AC_FUNC_ERROR_AT_LINE, AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK, AC_FUNC_MKTIME, AC_FUNC_STRTOD as obsolete and refer to Gnulib. * NEWS: Mention the change. --- NEWS.orig Sat Aug 28 11:46:36 2010 +++ NEWS Sat Aug 28 11:42:54 2010 @@ -25,6 +25,14 @@ ** Autotest testsuites should not contain long text lines any more, and be portable even when very many test groups are used. +** Newly obsolete macros + The following macros have been marked obsolete.
