Compilations warnings on OSX with clang

[urkle]

When compiling with clang on OS X this warning is produced. this should be std::abs (or fabs)

src/eval.cpp:34:50: warning: using integer absolute value function 'abs' when argument is of floating point type
      [-Wabsolute-value]
  inline double mod(double x, double y) { return abs(fmod(x, y)); } // x/0 checked by caller
                                                 ^
src/eval.cpp:34:50: note: use function 'std::abs' instead
  inline double mod(double x, double y) { return abs(fmod(x, y)); } // x/0 checked by caller
                                                 ^~~
                                                 std::abs

Although I cannot reproduce this on OSX I agree with the conclusion. In the future please provide enough system information for a reproduction.

Will do.. Ideally I'd be including a patch as well :) FYI.. (Xcode 6.4)
