I agree that a #define is better than just having the number 10
sitting in the code, though I think consts are better, and #defined
constants as Szilard uses above are better than macros that look like
functions (c.f. the Linux kernel style guide for C).  If we must do
this, I would suggest, however, that we use names that are slightly
longer, more suggestive of the purpose, and have fewer potential
namespace collisions with other libraries. :)
