Hmm. Is it possible to fool it by adding more static variables in
OMNI_FORCE_LINK?  Or perhaps a static function that references the
linked symbols. I'm not keen on the idea of adding code in function
bodies since that doesn't work well for things like the extra code
sets library and the SSL transport.

Are there any compiler switches to tell it not to remove things that
aren't referenced?

Cheers,

Duncan.
