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:


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