           Summary: [4.6] can't bootstrap with ada, java and go on mingw
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target

              Host: mingw
            Target: mingw
             Build: mingw


Bootstrapping gcc 4.6 r170503 on mingw with ada, java and go enabled and the
following configuration fails with several errors.

seems to need some more rework for mingw. From this point I turned off the go

--- Comment #1 from Kai Tietz <ktietz at gcc dot gnu.org> ---
go language isn't supported for mingw targets (see PR/47726).
The other languages should work with newer gcc versions.
gcc 4.6 isn't no longer maintained, so I close this bug.
