            * decl.cc (char_len_param_value): Fix memory leak.
            (resolve_block_construct): Remove unnecessary static decls.
            * expr.cc (gfc_is_ptr_fcn): New function.
            (gfc_check_vardef_context): Use it to permit pointer function
            result selectors to be used for associate names in variable
            definition context.
            * gfortran.h: Prototype for gfc_is_ptr_fcn.
            * match.cc (build_associate_name): New function.
            (gfc_match_select_type): Use the new function to replace inline
            version and to build a new associate name for the case where
            the supplied associate name is already used for that purpose.
            * resolve.cc (resolve_assoc_var): Call gfc_is_ptr_fcn to allow
            associate names with pointer function targets to be used in
            variable definition context.
            * trans-decl.cc (gfc_get_symbol_decl): Unlimited polymorphic
            variables need deferred initialisation of the vptr.
            (gfc_trans_deferred_vars): Do the vptr initialisation.
            * trans-stmt.cc (trans_associate_var): Ensure that a pointer
            associate name points to the target of the selector and not
            the selector itself.
