        PR fortran/20896
        * interface.c (check_sym_interfaces): Try to resolve interface
        reference as a global symbol, if it is not a nodule procedure.
        (compare_actual_formal): Remove call to gfc_find_symbol; if
        the expression is already a variable it is locally declared
        and this has precedence.
        gfortran.h : Add prototype for resolve_global_procedure.
        resolve.c (resolve_global_procedure): Remove static attribute
        from function declaration.
        (resolve_fl_procedure): Remove symtree declaration and the
        redundant check for an ambiguous procedure.

        PR fortran/25135
        * module.c (load_generic_interfaces): If the symbol is present
        and is not generic it is ambiguous.
