           Summary: Compilation error on AIX52
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org

Running on AIX52. Using gcc make 3.80 and binutils 2.14. (Also fails without 
binutils). Using a prebuilt version of gcc 3.3.1 for AIX51 to compile.
Just using --prefix for configure options. Everything is OK up to the gcc 
point. This generates the following:
