I haven't tried to build Boost yet with the CodeWarrior command line
tools. I was using the IDE to build the threads library. I used
"boost/config.hpp" for the prefix file (which means it's
automatically included before anything else) which seems like the
right thing to do.

As best I can determine what happens is that posix_features.hpp
defines BOOST_HAS_PTHREADS because _POSIX_THREADS is defined. But
suffix.hpp doesn't define BOOST_HAS_THREADS because none of __MT__,
_REENTRANT, or _PTHREADS are defined. CodeWarrior currently doesn't
provide single-threaded runtime or C/C++ libraries so maybe one of
these should be defined on Mach-O...
