>Description:
c++error.ii 
-----------------------------
template <class A> 
class a {
};

int main() {
   a<a<int>> blah;
}
-----------------------------
when compiled on mainline cvs - gives
-----------------------------
c++error.cc: In function `int main()':
c++error.cc:6: error: template argument 1 is invalid
c++error.cc:6: error: template argument 1 is invalid
c++error.cc:6: error: expected `;'
------------------------------
correct - but nowhere near as nice as previosly
gcc version 3.2.2 20021212 (Debian prerelease) gives
------------------------------
c++error.cc: In function `int main()':
c++error.cc:6: `>>' should be `> >' in template class name
------------------------------
>How-To-Repeat:
g++ -c c++error.ii
>Fix:
unknown
