the problem is that some failures are are unanticipated.
For example, some standard library function might not
be working on some platform. The test just bails.

hmmm - then what is the problem? is this not being used? or
is there some other reason it's not being used. Does it
really work with no surprises?

hmmm wouldn't this required making the bjam files even more
elaborate than they already are? I'm reluctant to start messing
with things once they start working as I've found Jamfile hard
to understand and debug - especially when they're running
on some test system far removed from me. I know there's no
solution to this - I'm just mentioning that I don't think this is
practical for "the rest of us"
