I tested the problem with this simple snippet:

#include <boost/minmax.hpp>
int foo() { return boost::std_min(3, 4); }

The error goes away when I replace

using std::min;
return min BOOST_PREVENT_MACRO_SUBSTITUTION ( a, b );

by

return std::min(a, b);

in boost/minmax.hpp. (This would, of course, break
other compilers/libraries) gcc-2.95.3 without STLPort
doesn't require that change, but works fine with it, too.
