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.
