BOOST_MIN() and BOOST_MAX() now live in minmax_macro.zip at:
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
Thanks go to Howard Hinnant for feedback and test cases.
