My goal was to choose short names, as otherwise preprocessing lines easily become enormous (if nothing else, it's a boost guideline to not exceed 80 characters). Note that even things like:

#if BOOST_MSVC >= 1200

are usually rewritten as

#if defined(BOOST_MSVC) && BOOST_MSVC >= 1200

just because gcc warns about the first form when using -Wundef. And something like

#if defined(BOOST_GCC_CXX_VERSION) && BOOST_GCC_CXX_VERSION >= 295

is already 66 characters.

Isn't there a BOOST_WORKAROUND macro for this? e.g. #if BOOST_WORKAROUND( BOOST_MSVC, >= 1200 ) #if BOOST_WORKAROUND( BOOST_GCC_CXX_VERSION, >= 295 ) Regards, Reece _________________________________________________________________ Express yourself with cool emoticons - download MSN Messenger today! http://www.msn.co.uk/messenger
