Is there interest in turning this into a BOOST_MIN/BOOST_MAX library? [TRUNCATE the actual code]
Yes, please.
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. -- Eric Niebler Boost Consulting www.boost-consulting.com
