19 | /* If at all possible, fix the source rather than using these macros |
20 | to silence warnings. If you do use these macros be aware that | |
21 | you'll need to condition their use on particular compiler versions, | |
22 | which can be done for gcc using ansidecl.h's GCC_VERSION macro. | |
23 | ||
24 | gcc versions between 4.2 and 4.6 do not allow pragma control of | |
25 | diagnostics inside functions, giving a hard error if you try to use | |
26 | the finer control available with later versions. | |
27 | gcc prior to 4.2 warns about diagnostic push and pop. | |
28 | ||
29 | The other macros have restrictions too, for example gcc-5, gcc-6 | |
30 | and gcc-7 warn that -Wstringop-truncation is unknown, unless you | |
31 | also add DIAGNOSTIC_IGNORE ("-Wpragma"). */ | |
