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. |
