Log message:
        * m4sh.m4 (_AS_UNSET_PREPARE): New macro, eved from
        _AC_INIT_PREPARE_ENVIRONMENT, and fixed: set `FOO' before trying
        to unset it: `unset' exits 1 if the variable is not defined.
        (AS_UNSET): Require it.  Use `as_unset' not `ac_unset'.
        * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): Use it.
