--with-jmh is an optional configure flag, not sure what we could do to
warn here. Perhaps there's some way to ensure certain make targets
depend on the configure having been run with the necessary prerequistes.
Sounds like a fine enhancement.

Sounds like a bug.

There should be support in the build system _somewhere_, but adding a
native library to a microbenchmark might still be a non-trivial
enhancement to the current implementation. It'd be a great addition,
though. I might have time to help out sometime soon, but I've got my
hands full right now. Perhaps someone else on this list could advice?
