--- Comment #2 from Alejandro Colomar <colomar.6.4.3 at gmail dot com> ---
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-header=
s`
for that macro.=
