Unfortunately I don't see these warnings with the compiler I have
available with the settings that are currently available.  Do you know
of what to enable these warnings in gcc or Clang?

The nature of these warnings are such that I really need to be able to
see the warning first hand and attempt a local fix to see the affect.

Cheers,
Robert.
