BOOST_MIN() and BOOST_MAX() now live in minmax_macro.zip at:

http://boost-consulting.com/vault/index.php?directory=Algorithms

and also in boost-sandbox CVS at boost/algorithm/minmax_macro.hpp. It's 
been tested with gcc 3.x and msvc 7.1, and I took a stab at a version 
for Comeau, but which is currently untested.

This code pokes into C++'s dark, dusty corners, and no two compilers 
seem to agree, so any feedback/workarounds for other compilers is much 
appreciated.

Thanks go to Howard Hinnant for feedback and test cases.
