     8  // Compiler/library version workaround macro
     9  //
    10  // Usage:
    11  //
    12  //   #if BOOST_WORKAROUND(BOOST_MSVC, < 1300)
    13  //      // workaround for eVC4 and VC6
    14  //      ... // workaround code here
    15  //   #endif
    16  //
    17  // When BOOST_STRICT_CONFIG is defined, expands to 0. 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.
