But you're not compiling with MinGW, are you?

Honestly, VC++ is an evil if you're playing with C++.

Back to the problem, here you have the explanation:
http://msdn.microsoft.com/library/en-us/vccore/html/vclrfminmaxdefinechange.asp
http://babbage.cs.qc.edu/STL_Docs/algorithm_min.htm

Simply, std::min and std::max simply don't exist in the VC6 version of
STL, because it's a very old and not ISO C++ Standard compliant STL.

AFAIR, you won't be able to build GEOS using Visual C++ 6.0.
For example, geos uses in-place initialization of static const integer
data members, what feature is not supported by VC++ < 7.1 (Visual C++ 2003).

FYI, Recommended version of C++ compiler from Microsoft starts from
Visual C++ 2003 (7.1).
