If you want to be at the bleeding edge, you can give it a try. I've
uploaded this code as Vault/Units/mcs_units_hetero_op.zip. I think it
should work on non-g++ compilers (but _without_ heterogenous operator
functionality), but no guarantees. Everything except power<N> and
root<N> seems to work for me. Try unit_example_6.cpp to get a feel
for it...
Cheers,
