/* 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").  */
