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"). */
