		  stabs           DWARF-2
  GCC 2.95        pass            fail
  GCC 3.x         fail            pass

Do gcc 2.95.3/dwarf-2 and gcc 3.x/stabs+ have identical output,
or different output?

If they are different output, you can do:

  send_gdb "blah"
  gdb_expect {
    -re "good output" {
      pass ...
    }
    -re "flaky gcc 2.95.3/dwarf-2 output" {
      setup_xfail_format "dwarf-2"
      fail ...
    }
    -re "flaky gcc 3.x/stabs+ output" {
      setup_xfail_format "stabs+"
      fail ...
    }
    -re ".*" {
      fail ...
    }
  }

You can also dynamically poke at the executable to see what gcc compiled
it.  See "probe_demangler" in gdb.c++/cplusfuncs.exp for one way to do it.
