	typedef int (*PF)();
	class foo_c { PF fp; public: void m(); };
	void foo_c::m() { return fp(); }

G++ 1.35.0 produces the error message 'component `fp' is not a method'.

There appears to be a logic error in the function hack_identifier in
cplus-method.c, which persists in G++ 1.35.1 (which we aren't running
since we're waiting for 1.36.0).  The special case of a data member
that is a pointer to a function or to a member function is incorrectly
recognized; here's the fix I made:
