/* If at all possible, fix the source rather than using these macros

to silence warnings. If you do use these macros be aware that

you'll need to condition their use on particular compiler versions,
|
|
which can be done for gcc using ansidecl.h's GCC_VERSION macro.
|
|
|
|
gcc versions between 4.2 and 4.6 do not allow pragma control of
|
|
diagnostics inside functions, giving a hard error if you try to use
|
|
the finer control available with later versions.
|
|
gcc prior to 4.2 warns about diagnostic push and pop.
|
|
|
|
The other macros have restrictions too, for example gcc-5, gcc-6
|
|
and gcc-7 warn that -Wstringop-truncation is unknown, unless you
|
|
also add DIAGNOSTIC_IGNORE ("-Wpragma"). */
