>Description:
When I try to compile the code given, I get an internal compiler error.  I can't test it on a proper gcc easily, so this is only in djgpp.  So if you can't reproduce it straight away, chuck this report in the bin.

Note no workaround is needed - the code is stupid, I just thought it still shouldn't generate an internal error.

Attempted compile with 'gxx -c a.cc', got:

a.cc: In instantiation of `Pow<0>::In<0>':
a.cc:9:   instantiated from here
a.cc:9: Internal compiler error in resolve_offset_ref, at cp/init.c:1891
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
>How-To-Repeat:
template <int N>
struct Pow {
  template <int Val>
  struct In {
    enum { value = Val * Pow<N-1>::In };
  };
};

Pow<0>::In<0> a;
