--- Comment #4 from nightstrike <nightstrike at gmail dot com> --- (In reply to Andrew Pinski from comment #3) > So this is not related to nested functions at all (just in case people > thought it was): It's also not due to flexible array members, given the change from 5 members to an array. I only mention it because I've submitted a report in the past about a different warning that was affected by that feature of C.
