        * resolve.c (flag_fn_result_spec): Correct a typo before the
        function declaration.
        * trans-decl.c (gfc_sym_identifier): Boost the length of 'name'
        to allow for all variants. Simplify the code by using a pointer
        to the symbol's proc_name and taking the return out of each of
        the conditional branches. Allow symbols with fn_result_spec set
        that do not come from a procedure namespace and have a module
        name to go through the non-fn_result_spec branch.
