Ian Lance Taylor 8aa9161e47 With the changes to support automatic forward declarations of
type names, gccgo no longer reports redefinition errors for
:=, because it no longer knows at parse time whether the type
has changed.  Adjust this test to not match "redefinition",
and to instead match gccgo's current output.
