std::swap

I was handed this piece of "cross platform" code and Xcode is complaining on compile:

The code:

  template < class Matrix_ > static void transpose ( Matrix_ &m )
  {
    std::swap ( m[1],  m[4]  );
    std::swap ( m[2],  m[8]  );
    std::swap ( m[3],  m[12] );
    std::swap ( m[6],  m[9]  );
    std::swap ( m[7],  m[13] );
    std::swap ( m[11], m[14] );
  }

The Compile Error:
/Usul/Math/Matrix44.h:143: error: 'swap' is not a member of 'std'

I have used stuff from std before.. Is there an include that I need to do?


Alternatively if some nice soul would like to point me to the AltiVec function that can simply transpose a 4x4 matrix of floats, that would be nice. Tried looking in BLAS but there does not seem to be any easily reachable documentation to read.
