If macros are implemented in 3.1 in about the same way they are in the
isosurface patch, then the recursion limit on macros is the same as the 
recursion limit on include files, so that (# of includes + # of macros)
can't be greater than 10.  Of course, there are significant differences 
between the syntax of the two methods, so it's possible that the 3.1 
implementation is more flexible.  It's also possible that they increased
the limit on the number of include files, since changing it is just a 
matter of changing a single number in tokenize.h and recompiling.
