#ifndef WORKAROUND_DWA2002126_HPP | |
# define WORKAROUND_DWA2002126_HPP | |
// Compiler/library version workaround macro | |
// | |
// Usage: | |
// | |
// #if BOOST_WORKAROUND(BOOST_MSVC, < 1300) | |
// // workaround for eVC4 and VC6 | |
// ... // workaround code here | |
// #endif | |
// | |
// When BOOST_STRICT_CONFIG is defined, expands to 0. Otherwise, the | |
// first argument must be undefined or expand to a numeric | |
// value. The above expands to: | |
// | |
// (BOOST_MSVC) != 0 && (BOOST_MSVC) < 1300 | |
// | |
// When used for workarounds that apply to the latest known version | |
// and all earlier versions of a compiler, the following convention | |
// should be observed: | |
// | |
// #if BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1301)) | |
// | |
// The version number in this case corresponds to the last version in | |
// which the workaround was known to have been required. When | |
// BOOST_DETECT_OUTDATED_WORKAROUNDS is not the defined, the macro | |
// BOOST_TESTED_AT(x) expands to "!= 0", which effectively activates | |
// the workaround for any version of the compiler. When | |
// BOOST_DETECT_OUTDATED_WORKAROUNDS is defined, a compiler warning or | |
// error will be issued if the compiler version exceeds the argument | |
// to BOOST_TESTED_AT(). This can be used to locate workarounds which | |
// may be obsoleted by newer versions. | |
