--- Comment #1 from nightstrike <nightstrike at gmail dot com> --- It looks like the other testsuite changes (attr-8.c, the objc/c++ tests, etc.) should be evaluated and ported over also, so this isn't a complete fix. Alternatively, maybe this would scale better in the future if the ms_ tests were integrated into the non-ms_ tests, with a macro to set the format checking attribute between gnu_attr_printf and ms_printf.
