        * objc-act.c (objc_get_protocol_qualified_type): detect cases
        where we are asked to attach a protocol to something which is not
        an Objective-C object type, and produce an error.

        * objc/compile/20060406-1.m: Fixed testcase not to try to qualify
        a pointer to an arbitrary C struct with an Objective-C protocol.
        Test various valid uses of typedef with Objective-C objects and
        protocols instead.
        * objc.dg/invalid-type-1.m: New.
        * obj-c++.dg/invalid-type-1.m: New.
