High-Performance Math Routines The CUDA Math library is an industry proven, highly accurate collection of standard mathematical functions. Available to any CUDA C or CUDA C application simply by adding “#include math.h” in your source code, the CUDA Math library ensures that your application benefits from high performance math routines optimized for every NVIDIA GPU architecture.

This is actually quite interesting and works differently on Microsoft Visual Studio 2008 and Dev C++(using mingw);
1. Microsoft Visual Studio 2008cmath is basically a wrapper that calls math.h.
In math.h if running in C mode you only get one power function pow(double, double).
In C++ mode (which we are using) you get the c++ overloaded functions:
long double pow(long double,int), float pow(float,int), double pow(double,int) and a few others.
So calling pow(int, int) for example pow(3,2) will always fail due to ambiguity whether you include cmath or math.h
2. DEV C++ with MINGW
With this set up, math.h just contains the the usual C function
pow(double, double) - so all the functions work because with pow(int, int) both ints get promoted to double by compiler and all is OK
cmath in more than a wrapper for math.h. First it includes math.h and then undefines a whole lot of stuff that math.h defined, and substitutes the c++ versions.
This includes the pow function declaration.
As the c++ overloaded functions (same as any other c++ compiler), you will get the ambiguity problem - when using pow(int, int).
P.S The ambiguity occurs with pow(int, int) because integers can be promoted to floats or doubles, which means that pow(int, int) can fit any of the 6 or so overloaded c++ pow function - so the compiler gets confused.
