Hi John,
as far as Boost.Build V2 is concerned, boost include directory and TR1 include 
directory as the same, they are both specified using <include> feature, and 
no specific order is guaranteed.

I think V1 has <sysinclude>, but I never seen any explanation how it's 
different from <include>. Probably <sysinclude> appear before <include> and 
that's making it working in V1.

Can somebody confirm that?

Alternatively, I can try to revive the mechanism for controlling includes 
order, that will allow you to write:

  <include>$(BOOST_ROOT)&&$(BOOST_ROOT)/boost/tr1/tr1

And have $(BOOST_ROOT) and $(BOOST_ROOT)/boost/tr1/tr1 appears in exactly this 
order.
