>From looking at the source, the call to split-target-subvariant is made with
the list of available subvariants to build for the library. I think this
means things like single/multi-threaded, dynamic/static linking. The problem
comes because there are no available subvariants for serialization on Borland
and vc-6_5 targets, so bjam complains that there is a missing parameter.

I would be interested to see how to do this.

Definitely. Anyone more knowledgeable in Boost.Build care to help?
