--- Comment #3 from Kai Tietz <ktietz at gcc dot gnu.org> --- Hmm, what I don't get is why there is a warning about -mno-fentry. So I would assume there is something else broken. Nevertheless this reminds me about pr/57848. This issue seems to be in general no mingw specific problem, but more an inconsistency about sse and builtins.
