Usually, this is related to stricter standards conformance by g++. On
your case, maybe there is a `typename' missing, like this:

throw TestFailure( typename Print< IsStreamable< T >::result &&
                          IsStreamable< U >::result,
                          IsEqualFunc >::Out< T, U >( lhs, rhs,
                          lhscode, rhscode ),
                          line, file );

but it is hard to say for sure. We need a complete test case. (As
short as possible).

You could try gcc 3.4.x to see if it is a bug on 3.2.x.

OTOH, this error:

../src/testfuncs.cpp:2:29: no newline at end of file

has an obvious fix. The C & C++ standards requires a newline at the
end of each translation unit.
