        * trans-common.c (gfc_trans_common): If the blank common is
        in a procedure or program without a name then proc_name is null, so use
        the locus of the common.
        (gfc_sym_mangled_common_id): Fix whitespace.
        * match.c (gfc_match_common): Emit warning about blank common in
        block data.
