| 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 |

| 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"). */ |
