            Bug ID: 69475
           Summary: [x32][6]: FTBFS: configure: error: cannot compute
                    sizeof (long long)
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---
            Target: x86_64-linux-gnux32

Hello!

gcc-6 fails to build from source on x86_64-linux-gnux32 (Debian) as apparently
the size of (long long) is not properly defined:

checking for long long... yes
checking size of long long... configure: error: in `/«PKGBUILDDIR»/build/gcc':
configure: error: cannot compute sizeof (long long)
See `config.log' for more details.

Full log available on buildd.debian.org [1]. So far, gcc-6 hasn't been built on
x32 because of this.

Cheers,
Adrian
