Two years ago I submitted a patch that made the `ms_printf` attribute accept `%lld`, so there is now a universal modifier for `long long`. The issue here looks like that `printf` , which is a 'well known' function to GCC, has a pre-defined attribute. If a new `*_printf` attribute is declared, it gets both, as pointed out by Andrew Pinski.
