You probably will run into that problem, but you haven't gotten that far 
yet.  This one is a more general C++ error saying that it can figure out 
what is supposed to be used for this statement because of ambiguities 
related to the data types used.  I'm not sure why that is not happening 
for other 64-bit compilers however...
