// GROUPS passed copy-ctors
/*
g++ 2.3.3 will prefer using type conversions over the
implicitly generated copy constructor. This is wrong.
If you explicitly define a copy constructor, it will
use it. However, the implicit copy constructor MUST be
called whenever an explicit one would have been called
also. See below: g++ converts from and back into
unsigned, instead of using the implicit copy constructor:
