A quite simple array specialization construct is rejected by g++ with a
compiler error message. Not being a language specialist icc 9.1 accepts the
code even with -strict-ansi flag. Allegedly also comeau accepts the code. The
g++ compiler error message is also pretty strange and indicates a compiler bug.

template<typename T>
struct x {};

template<typename T, unsigned N>
struct x<T*[N]> {};

int main() {
  x<int> a;
  x<int*[10]> b;
  return 0;
}

bash> g++-4.1.2 -c tst.cpp
tst.cpp:7: error: template parameters not used in partial
specialization: tst.cpp:7: error:         ‘T’

I'm unable to create attachments, bugzilla crashes. I have reported the
bugzilla bug also to dberlin@gcc.gnu.org.
