I've just found very similar issue in other place. It is std::pow
specialisations seem ambiguous for Comeau C/C++ compiler.

"../../../boost/math/special_functions/spherical_harmonic.hpp", line 39:
error:
          more than one instance of overloaded function "pow" matches the

I thought it may be of interest.
