State-Changed-Why:
    Confirmed. Though it's worse: gcc3.2.3 and 3.3 ICE on this
    code. 3.4 doesn't any more. But I think that we have other
    reports about the ICE, so we may keep this PR just for the
    problem with the diagnostics. Is this right Giovanni?

 Exactly. This is what I meant at the start of the PR description.

>Description:
This is the testcase for c++/10705 (a 3.3 only regression):

-------------------------
template <typename T>
struct X<T*> {
   typedef int Y;
};
-------------------------

Compile with 3.4, we get:

pr10705.cpp:4: error: expected unqualified-id

This is a regression on error diagnostic wrt 2.95, where
it was giving:

pr10705.cpp:2: `X' is not a template
pr10705.cpp:2: template class without a name

which is much clearer. With Comeau, I get:

"pr10705.cpp", line 2: error: a template argument list is not allowed in a declaration of a primary template
  struct X<T*> {
         ^
