A define is needed to expose the M_PI define from the system headers.

It seems like the other places where we depend on M_PI, we instead have

#ifndef M_PI
#define M_PI 3.14159265358979323846
#endif

Perhaps that's a better solution?

Oh. I actually did that for my quick-n-dirty fix and thought it would be
rejected so I researched the other one :-) either one is fine by me.
