[C++ PATCH] Fix 2368

[Nathan Sidwell]

Hi,
I've installed this obvious patch on both mainline and branch
which fixes 2.95 regression 2368.

We try and warn about shadowed catchers, but should only do so on
real classes, not things which might be classes (like template types).

built & tested on i686-pc-linux-gnu.

	typename types etc.
