[Boost-build] Overriding the type of a source file?

Before I go and hack BB  to support this I'm wondering if someone knows if
it's already possible.. I'm doing some BB files for an external library
(Cinder) and it has one unfortunate aspect that I need to deal with. It has
*.cpp files that are actually Objective C++ files on OSX, and plain C++ on
other platforms. So the basic question is:

Is there an existing way to indicate the source type irrespective of the
file extension?

And if not.. Any suggestions as to what the best way to implemented such an
option would be?

Rene.
