Currently this is not possible. But (as one of the boost.test
maintainer) I see this as an important feature for boost.test, so I'll
be working on it.

The main chunks of dependencies boost.test relies on are:
- boost.config that indicates many of the compiler capabilities. I
believe we can come up a header that the user can adapt from a general
one (as some autoconf like tool would do)
- boost.mpl that can be replaced by c++11 features
- boost.preprocessor that is heavily used for getting the macro magics.

Apart from that, there are many utility functions, as John said for
instance boost.chrono and boost.timer. I do not have a clear strategy
for this, apart from duplicating those within boost.test.

I understand that this is an urgent feature for you, although I cannot
commit to a precise date, I will work on this.
