Something just crossed my mind - while looking at the bjam build with
the -d+2 set, it seemed to have all the stlport paths etc.
Does boost build with the gcc-stlport setting redefine _STL as std, and
so even though the examples have std:: in them, it's really STLPort?
(and I shouldn't be doing using namespace _STL)?
