I am pretty sure it is a Unix only thing, i tried to compile a game that
used the M_PI macro and the compiler complained. I think that PI works
on windows machines but im not sure. If it doesnt, just add the
following code:

#ifndef M_PI
#define M_PI           3.14159265358979323846  /* pi */
#endif
