            Bug ID: 65535
           Summary: powerpc64-freebsd build failure
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org

Building gcc for powerpc64-freebsd fails with the error below.  Looks like the
FBSD_MAJOR macro is defined to nothing:

$ grep FBSD_MAJOR ./gcc/tm.h
#ifndef FBSD_MAJOR
# define FBSD_MAJOR

Defining the macro to an integer such as 10 lets the build succeed.
