The answer is complex. On most systems and in most cases, the answer
is "no". However, if any code that is compiled into the executable,
such as inline functions in a's or b's headers or template functions
there, directly refer to symbols from 'a', then, on Windows, you
have to list both a and b. This is pretty confusing behaviour, so
probably should be fixed in Boost.Build -- let me know if you
actually run in this problem.
