c++ - member template class bug

This is a bug, but to be fair to DMC, very few compilers allow the
out-of-class definition of functions of nested template classes. Because of
this, there are very few code bases that will be looking for such support
from compilers, so I guess its legitimate for Walter to not have dealt with
this one yet.

On the other hand, we know how he likes to provide things before other
vendors can ...
