That sounds reasonable to me: if people wish to use Boost.Thread
header-only then they can define the macro, but anyone who needs to use
the full features must link against the library, so can cope with the
additional dependency on Boost.System.
It would be great if we could ensure that code with incompatible
settings wouldn't link. We could mask out the parts of Boost.Thread that
do need the library with that macro, for starters, so we don't need
separate builds of the library with and without that macro.
