So again, I'd say if this is a non-conflicting COMPILE_TEST option (ie,
enabling it doesn't for anything else to be disabled), you might as well
enable it without a prompt on COMPILE_TEST. But that's just me. :)

If folks really disagree, and there is to be a user prompt, can we get
just a little more detail in the help text?
So what is the CMT hardware? Maybe what does CMT stand for? What
hardware is it frequently found on?

thanks
