Perfectly legal.
That is a static member of SGLimits<T> that is basically the same than
std::numeric_limits. That in turn has a min static member.
On windows, you have that nasty windows.h header defining a min and max macro
that will interfere with the ISO C++ standard.
Dig into the windows headers, there is a way to avoid windows.h defining that
macro.
