--- Comment #39 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Ok, so what do we want to do on the gcc side?
Nothing, just tell users they need latest binutils?
Or try to add a configure check to detect broken binutils that doesn't hand=
le
the DWARF5 new sections and if it detects broken binutils, in
ix86_option_override_internal if (TARGET_PECOFF && dwarf_version > 4) and
#ifdef the new macro about broken pecoff binutils set dwarf_version to 4
(if !global_options_set.x_dwarf_version silently, otherwise with a warning =
(but
perhaps just once per the whole TU))?
As I have no access to Windows, I'm afraid I can't easily write a configure
test myself, I can help with the i386-options.c change if needed, but can't
test anything.=
