Re: SWARM problems

[Doug Donalson]

Yes, I get this also.  It happens, sometimes, when following a set include files
wraps around on itself.  ie A needs to know about B, B needs to know about C, C
needs to know about A.  BUT... C claims that it can't find a definition of A.
This does not happen in every case of "wrap-around include definitions".

So, members of the Hive, inquiring minds want to know, how do we avoid this?

Cheers,
