I missed this patch in my earlier sweep looking for patches from
coreutils/gnulib into autoconf.  I installed it now.

        * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
        Import the following fix from coreutils:

        2006-01-13  Jim Meyering  <address@hidden>

        Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
        $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
        not double-quote uses of that variable, to accommodate the rare
        case in which getmntent is available in none of the libraries
        checked.  This happens at least on FreeBSD 5.0.
