I just pushed the ERRCODE_ macros out into their own file.  How about
placing that file where client apps can include it directly?

Note though that I think client apps will want to test "is this code in
this class" about as often as they'll want to check for specific
codes.  We might need to provide some additional infrastructure to
handle that.
