Optimizer bug in Visual Studio

Bruce Dawson posted about an optimizer weakness in VC++.

Using macros to implement Min and Max has numerous well known pitfalls that can be avoided by using template functions. However the definitions of min and max that are mandated by the C++ standard cause VC++ to generate inefficient code. Until the VC++ compiler fixes this it may be best to use custom Min/Max template functions to avoid this problem.
