--------------------------
template<typename T>
struct X {
    X (int);
};

template<typename T>
X<T>::X (int i __attribute__ (())) {}
---------------------------

This didn't ICE in 2.95, but does so in 3.2 and 3.3:

g/x> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -c x.cc
x.cc:7: error: parse error before `__attribute__'
x.cc:7: internal compiler error: in poplevel, at cp/decl.c:1296
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

It's fixed in 3.4 though.
