             Bug #: 54373
           Summary: [4.7/4.8 Regression]: build fails for
                    mmix-knuth-mmixware libobjc GCC_NO_EXECUTABLES
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: build, ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hp@gcc.gnu.org
              Host: x86_64-unknown-linux-gnu
            Target: mmix-knuth-mmixware


Some time after the 4.6 branch building binutils separately (not in a combined
tree) broke.  A build of binutils, installing that, then building gcc with PATH
including the binutils installation now results in:

(building gcc, then most other things including newlib, libstdc++, then:)

(gcc-4_7-branch revision 190562)

Similarly for trunk, for example revision 190649.

For failing versions, I see in gccobj/mmix/libobjc/config.log traces of basic
compilation problems:

thus I label this a target problem (maybe even a binutils and not gcc problem),
though the libobjc failure is far from gracious.
