gcc is complaining about an ambiguous overloading of operator&&
in the statement (last non-trivial line)
    return std::pow(a,2.0);

where no such operator appears. (I haven't seen a macro definition of 'pow'
which pulls in '&&')

If I replace the statement above by
    return ::pow(a,2.0);

the error disappears.

The function 'pow' should be injected into namespace 'std'
when doing
#include <cmath>

or am I missing something?
