The following patch gets the octonion / quaternion tests building with
gcc3.3 (the using declaration changes appear to be a gcc bug, the
static_cast changes appear to be required for classes with explicit
constructors as is the case here):

However while these patches are harmless for vc7.1 (the only compiler
currently passing these tests I think, there are still runtime failures with
gcc:

Which all look rather worrying, anyone any ideas what's going on here?
