>Description:
Nathan, I believe that this started with your patch from
2003-03-22 fixing PRs 9978 and 9708. Here's a little piece
extracted from boost that since breaks building my library:
-----------------------------
template <bool B> struct X {
    struct I {};
};

template <typename T> struct Y {
    static const bool selector = true;
    typedef typename X<selector>::I helper;
};

Y<int> i;
--------------------------------
With this I get
deal.II/base> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c y.cc
y.cc: In instantiation of `X<Y<T>::selector>':
y.cc:7:   instantiated from here
y.cc:1: error: integral expression `Y<T>::selector' is not constant
y.cc:1: error:   trying to instantiate `template<bool B> struct X'
y.cc:2: error: integral expression `Y<T>::selector' is not constant
y.cc:2: error:   trying to instantiate `template<bool B> struct X'
y.cc:2: error: integral expression `Y<T>::selector' is not constant

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

I'm not so much concerned with the ICE, which I don't get
on my code, but with the handling of integral constants. I'm
pretty sure the code should actually compile.
