I'm certain that this is a compiler bug, but I've changed the type
name anyway.

omkdepend issues all sorts of spurious warnings. I don't think it's
worth fixing them all.

The compiler is correct -- I have declared the two struct types
outside the union, which minimises the code changes.

Hmm. That inheritance is actually meant to be public, but it doesn't
seem to make any difference on the compilers I've tried.

Unfortunately, we can't use reinterpret_cast since not all of our
target compilers support it. You'll just have to live with that
warning.

That is actually a bug!  It should be casting to
PortableServer::POAManager_ptr.

What line did the warning come from?  As far as I can see, all of the
casts to do with TypeCodes are safe, although not necessarily strictly
type safe.

Thanks for the reports,

Duncan.
