Possibly the latter. It is no macro (in C++), it is a templated
function. It's defined in /usr/include/c++/3.2/bits/stl_algobase.h:

  template<typename _Tp>
    inline const _Tp&
    min(const _Tp& __a, const _Tp& __b)
    {
      // concept requirements
      __glibcpp_function_requires(_LessThanComparableConcept<_Tp>)
      //return __b < __a ? __b : __a;
      if (__b < __a) return __b; return __a;
    }

And it is indeed defined in namespace std.

You are not by any chance trying to compile a Qt/KDE application? Just
have a look at the preprocessed code (use cpp instead of g++) at this
location. How does it look like? And what's the command you've used to
compile this file?
