It would be useful, just so that we know where they are going.

This is how the original cygwin testing was done - at a dos prompt.

For the moment, lets stick with the status quo.  Tests are required to 
work host==build.  Having a test work host!=build is an added bonus, but 
not a requrement.  We can hardly enforce host!=build when there's no way 
to test it and the return on investment is marginal.
