I don't think that's enough to ensure anything. If you change the Jamfile so
that different preprocessor symbols are defined, the build can be wrong. So,
I think making targets dependent on their Jamfile is the only way to go.

Worse, when you delete a header, a different header might be found instead,
but the build system can't detect it. :-(
