the following code is fairly similar to this bug, but it is rejected by g++
4.0.0:
x.cc:10: error: '(Arg1 + 1)' is not a valid template argument for type 'int'
because it is a non-constant expression
x.cc:10: error: 'value' is not a member of '<declaration error>'
is it a new bug? (accepted by comeau c++)
(NoBug1 and NoBug2 are workarounds)

template <int x> struct Id {
enum { value = x };
