--------------------------------------------+-------------------------------
 I am using i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build
 5666) (dot 3)

 The error is:

 /usr/local/include/boost/accumulators/statistics/weighted_p_square_quantile.hpp:178:
 error: call of overloaded 'abs(double&)' is ambiguous
 /usr/include/stdlib.h:146: note: candidates are: int abs(int)
 /usr/include/c++/4.2.1/cstdlib:143: note:                 long int
 std::abs(long int)
 /usr/include/c++/4.2.1/cstdlib:174: note:                 long long int
 __gnu_cxx::abs(long long int)

 The correct overload is from <cmath> but this is not included. I have
 tested that added the include fixes the problem.

 As a workaround, including <cmath> before
 <.../weighted_p_square_quantile.hpp> in your own source fixes the problem.
