No, this should be the kind of cast that just makes the compiler happy
and has zero effect on the generated code. In fact in this case all of
these forms should yield exactly the same output:
reinterpret_cast< Handle >( ... )
Handle( ... )
(Handle)( ... )
When in doubt, inspect the asm output. It's easy to do in CodeWarrior
and hopefully possible in GCC too.
