>Description:
The following is rejected by gcc 3.4 but accepted by icpc -ansi (who is I believe right in this case):

enum { val = 1 };

template <class T>
struct Bar
{
        static const int A = val;
        static const int B = A + 1;
};

this leads to

bellatrix:~/src/tests$ g++-3.4 -c cexpr.cpp 
cexpr.cpp:7: error: `Bar<T>::A' cannot appear in a constant-expression

substituting 1 for val solves the problem.
