Ok, I read again everything and I eventually got it. The part that was misleading me was: "It only has value as a comment unless BOOST_DETECT_OUTDATED_WORKAROUNDS is defined". It's not clear *what* it's treated as a comment. I thought it was meaning that BOOST_TESTED_AT was silenty ignored if BOOST_DOW was not defined, thus leading to: #if BOOST_WORKAROUND(BOOST_MSVC, <= 1300) The previous sentence might be rephrased to "When BOOST_DOW is not defined, the macro evaluates to != 0, which effectively activates the workaround for any version of the compiler. When BOOST_DOW is defined, it will issue a compiler warning or error if the compiler version exceeds the argument".
