[C++ patch]: anonymous typenames

[Nathan Sidwell]

Hi,
I've installed this patch which diagnoses some more violations of
7.1.5.3/1. In this case where you just have
	typename T::t;

this popped up in a recent report at
http://gcc.gnu.org/ml/gcc-bugs/2000-07/msg00640.html

built & tested on i686-pc-linux-gnu and approved by Mark
