Try:

        bjam toolset=gcc/include=foo/include=foo2 toolset=msvc/include=bar/include=bar2

As for documentation, it's tricky issue. It used to be documented, but I don't
want this to be too widely known feature, because this syntax causes some ambiguities
when you have slashes inside the value, and it would be nice to invent a different
syntax.
