Well, GLOB is not some black box, nor is it external code given to us.
Actually, it will try each element of BOOST_BUILD_PATH in order,
so there will be no problems with that. I'd only have to
dig CVS history to understand why the 'boost-build' rule
works the way it works now -- appending the argument rather than
prepending it.
