           Summary: A GCC release tarball can no longer be built without
                    bison/flex
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: bootstrap
        AssignedTo: kcook at gcc dot gnu dot org
        ReportedBy: kcook at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

After the recent checkins to fix PR10996, a GCC release or pre-release tarball
will not be able to built on a system without bison or flex.

In addition, a user without makeinfo will no longer get documentation generated.

I'm assigning this bug to myself and have a framework in mind for fixing it. 
Patches forthcoming in the next few days.
