--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, is this about debug info (which I believe shouldn't be needed), or missing
unwind info?
I presume the mingw unwind info isn't done through .cfi_* directives, so would
need to be written by hand.  How hard is that, and is this really a regression,
those snippets didn't exist before?
