I think you're on the right track, but you go too far. I believe
we want to set TYPE_DECL_SUPPRESS_DEBUG (TDECL) to 0 if TDECL is the
declaration for a class defined in the current compilation unit,
and 1 if the class is defined elsewhere.
You might try adding this somewhere in push_class:
 TYPE_DECL_SUPPRESS_DEBUG (decl) = 1;
and to undo this for classes we're actually compiling,
in make_class_data add:
 TYPE_DECL_SUPPRESS_DEBUG (TYPE_NAME (type)) = 0;
