So it is the compiler telling you that something might go wrong and you can
silence it with -Wno-psabi, which is a warning option. Moreover, as it stands
now, if someone has -Werror=psabi, the compilation will not stop and they might
get bitten by this. Moreover2, -w will not silence the note. I still
completely fail to see why it is a note and not a warning.
In any case, using diagnostic_report_warnings_p (location) should fix it.
