In that case, here is an (untested) patch to a recent Autoconf
snapshot that should fix the problem.

2001-09-28  Paul Eggert  <address@hidden>

        * doc/autoconf.texi (Limitations of Usual Tools):
        Document that some older sed implementations can't handle
        nested parenthesization.

        * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
        Don't use nested parenthesization.  This patch was originally
        suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
        but somehow it didn't get incorporated then.
