I don't think you can :(. I just looked at mkmf, and it looks like  
the only way to make an extension for ruby as far as mkmf is  
concerned with C or C++.  mkmf doesn't really look for anything  
dynamically, those constants seem to be more to save typing than  
anything else. :( It's too bad, it would be neat if mkmf was  
extendable in this manner.
