What do you mean by the latter? We are not checking executables into the
CVS... We could try to put the apporopriate jam build directory at the
head of the path before searching the path for bjam...

However, note that on my system "bjam" in the path is a .bat file which
eventually invokes the .exe.

I'm still not convinced that it's a problem... unless perhaps you're
saying that it causes the tests to be more complicated than neccessary?
If so, I agree. Why don't you just apply the patch you posted to the
jamming list last week?

Good choice.

I think it's important that any testing system supplies a verbose mode,
so you can watch it actually do something, even when it succeeds. A
successful test that gives no feedback is a little unsatisfying ;-)
