There are several build errors when building current master, for this 
test I used Mingw64:

* Context fails to build complaining about ml64 not being found, but 
since I'm building with gcc it really should be using as?
* Thread fails to build complaining about missing 
boost/utility/detail/result_of_iterate.hpp, this is a result of:

#define BOOST_PP_ITERATION_PARAMS_1 
(3,(0,BOOST_RESULT_OF_NUM_ARGS,<boost/utility/detail/result_of_iterate.hpp>))

In boost/utility/result_of.hpp, we could presumably fix this by adding a 
dependency that Boost.Build can actually track to this header. 
Presumably we should do the same for all header iterations?
* Coroutine fails for the same reason as thread.
* Header only libraries are not installed when doing a 
build/stage/install all, you have to explicitly invoke b2 headers.  IMO 
this will trip a lot of folks up.
* There is no mention of the "b2 headers" option from "b2 --help".

Question - I assume that if folks do a library-specific install then we 
*don't* want to install all headers?  Can we achieve that and yet make 
the equivalent of "b2 headers" happen if folks do a build all?

Cheers, John.
