| 10 | // Usage: |
|---|
| 11 | // |
|---|
| 12 | // #if BOOST_WORKAROUND(BOOST_MSVC, < 1300) |
|---|
| 13 | // // workaround for eVC4 and VC6 |

| 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. |
