That's fair.

This is an excellent idea.

Oh, believe me, I know all about the joys of running tests on VxWorks
boards.

Unfortunately I don't have a good answer for you.  I would *like* to
see the C and C++ testsuites run against a physical board, but since
I have never managed to make that work myself, I can't ask it of you.

There is a thing called WindISS which is relatively easy to make work
with gcc and dejagnu, but it's not simulating the real VxWorks
environment, alas.
