exp10 missing from non-GNU platforms

GNU libraries provide exp10 (which seems to provide some speed benefit) in . OS X (and presumably other BSD-based systems) do not provide this function.

Proposed

Do a function check for exp10 at configure-time. If it does not exist, define it as

inline double exp10(double val)
{
    return pow(10.0, val);
}

sounds fine to me.
