Please try

#include <math.h>

or

#include <cmath>

in the respective files. I'm not sure, but I think that it would be standards-
conforming if the first version would not populate the std-namespace and the 
second version would not populate the global namespace. However, I doubt that 
compilers are that unhelpful, so either should work.

Can't help you with that, sorry. But I'm pretty sure that Dirk tested it on 
MacOS.
