Compilation failure of HTTP connection - min/max defines problem on windows #12

While I tested on Windows using MSVC version 8.0, I had some compilation failures (beyond what has already been reported)

..\..\..\boost/network/protocol/http/connection.hpp(218) : error C2589: '(' : illegal token on right side of '::'

This is to do with the use of std::min. Boost library guidelines describe what can be done in this situtation:
