In gcc/:

* c-typeck.c (convert_arguments): Use warning 'too many arguments
        to method [methodname]' for an Objective-C method instead of the
        less satisfactory 'too many arguments to function' (with no method
        name).
In gcc/cp/:
        * typeck.c (warn_args_num): Use warning 'too many arguments to
        method [methodname]' for an Objective-C method instead of the less
        satisfactory 'too many arguments to function' (with no method
        name).
In gcc/testsuite/:
        * obj-c++.dg/too-many-args.mm: New file.
        Merge from 'apple/trunk' branch on FSF servers.
