0008 // Compiler/library version workaround macro
0009 //
0010 // Usage:
0011 //
0012 //   #if BOOST_WORKAROUND(BOOST_MSVC, < 1300)
0013 //      // workaround for eVC4 and VC6
0014 //      ... // workaround code here
0015 //   #endif
0016 //
0017 // When BOOST_STRICT_CONFIG is defined, expands to 0. Otherwise, the
0018 // first argument must be undefined or expand to a numeric
0019 // value. The above expands to:
0020 //
0021 //   (BOOST_MSVC) != 0 && (BOOST_MSVC) < 1300
0022 //
0023 // When used for workarounds that apply to the latest known version
0024 // and all earlier versions of a compiler, the following convention
0025 // should be observed:
0026 //
0027 //   #if BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1301))
0028 //
0029 // The version number in this case corresponds to the last version in
0030 // which the workaround was known to have been required. When
0031 // BOOST_DETECT_OUTDATED_WORKAROUNDS is not the defined, the macro
0032 // BOOST_TESTED_AT(x) expands to "!= 0", which effectively activates
0033 // the workaround for any version of the compiler. When
0034 // BOOST_DETECT_OUTDATED_WORKAROUNDS is defined, a compiler warning or
0035 // error will be issued if the compiler version exceeds the argument
0036 // to BOOST_TESTED_AT().  This can be used to locate workarounds which
0037 // may be obsoleted by newer versions.
