           Summary: bug building with option with-cpu
           Product: gcc
           Version: 3.3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dealer4587 at yahoo dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: powerpc-aix-4.3.3
  GCC host triplet: powerpc-aix-4.3.3
GCC target triplet: powerpc-aix-4.3.3

Building gcc 3.3.1 and 3.3.2 with option "with-cpu" will cause failure because 
the definition of "ASM_DEFAULT_SPEC" and "ASM_CPU_SPEC" in header 
files "aix*.h" and "rs6000.h" do not work properly and passing wrong 
parameter "-mcom" to IBM "as". Use this parameter will make the "as" can not 
assemble the specific cpu code genarated by compiler.
Some works has been done after the bug found several years ago, but now it 
still exist.
