The standard math header included here - <cmath> - does not inject math functions into the global namespace. The only standard way to use these functions (pow included) is via std:: namespace.
All the uses of pow should be converted to std::pow, otherwise compilers with strictly conforming standard headers (like SunCC) will not be able to compile.
std::pow works fine with all the compilers I tried (SunCC, g++).

Doh... pilot error. Is there a way to change bug summary?
Should read: "unqualified POW() fails to compile on SunCC/SunOS"
