Thank you kindly Stefan for responding, and yes my wording and interpretation of what is happening with the make command is very much lacking in accuracy.

The difference you demonstrated in stdout is exactly why there is now a question mark over the command to be used at this point. Is the functional intent of the differing commands completely separate/distinct?
Is one command more appropriate/correct than the other for use or are they to be used under separate context/criteria?

If someone offered you the painfully open statement: "Stefan, I'd like you perform the linking phase for 'ipc_rds'???" - which version of the command do you instinctively reach for? :)

Regards,
Ruan
