Otherwise, the 18 // first argument must be undefined or expand to a numeric 19 // value. The above expands to: 20 // 21 // (BOOST_MSVC) != 0 && (BOOST_MSVC) < 1300 22 // 23 // When used for workarounds that apply to the latest known version 24 // and all earlier versions of a compiler, the following convention 25 // should be observed: 26 // 27 // #if BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1301)) 28 // 29 // The version number in this case corresponds to the last version in 30 // which the workaround was known to have been required. When 31 // BOOST_DETECT_OUTDATED_WORKAROUNDS is not the defined, the macro 32 // BOOST_TESTED_AT(x) expands to "!= 0", which effectively activates 33 // the workaround for any version of the compiler. When 34 // BOOST_DETECT_OUTDATED_WORKAROUNDS is defined, a compiler warning or 35 // error will be issued if the compiler version exceeds the argument 36 // to BOOST_TESTED_AT(). This can be used to locate workarounds which 37 // may be obsoleted by newer versions. 38 39 # ifndef BOOST_STRICT_CONFIG 40 41 #include <boost/config.hpp> 42 43 #ifndef __BORLANDC__ 44 #define
