BTW, I was told that if boost/config.hpp is included before any system
headers, it will still be able to use _REENTRANT to detect if -pthread was
specified on the command line.

No, I don't know any. How would that help?
I'm not sure if such macro can be easily added in Boost.Build v1. In V2 it's
one-line change to top-level Jamfile, so I hope V2 will be ready to replace
V1 after we've done with the release.
