There's been some discussion of this issue at Apple.  I think we're 
leaning in the direction
of having the driver include -lmx automagically.  In fact I thought 
Andrew already had a
patch in that did this for C++.   Comments?
(An obvious question is, Why are they in libmx?  All I can tell you is 
the compiler people
don't control that...)
