/* 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"). */ |
