I noticed that when I don't include <boost/thread/thread.hpp> before the standard library includes, I get the following errors:

In file included from /fs/szattic-asmg6/rob/dist/include/boost/thread/lock_types.hpp:14:0,

/fs/szattic-asmg6/rob/dist/include/boost/thread/lockable_traits.hpp:114:37: error: expected identifier before ‘*’ token

However, when I move the boost thread include to the top of the set of included headers (above the standard library), the

program compiles and runs correctly.  What is the reason for this frustrating requirement?  Is it possible to eliminate this behavior, so that

<boost/thread/thread.hpp> can be included anywhere (or at least after the standard library) ?

Thanks,
