Other comments in the file gave me the impression that the pragma needs to
come before header includes (hence why it's not using the preferred macro
DIAG_IGNORE_NEEDS_COMMENT).

there seems to be no way to pacify GCC selectively, only for the
place where it's needed. Do not use DIAG_IGNORE_NEEDS_COMMENT
here, as it's not defined yet. */
