Maybe the design is not perfect.

Maybe some special warnings should still be warned about when they are used in
user's code.  I don't think there are any possible false positives with this
warning.  But still I don't know.

Maybe I should add a pragma in the system header to enable `-Wsystem-headers`
for that macro.
