            Bug ID: 72786
           Summary: Odd spelling suggestion with later defined macro:
                    Suggestion is identical to unknown identifier
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
                CC: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

The suggestion in the error message is odd:

inp5.ii:2:30: error: ‘OVERRIDE’ does not name a type; did you mean ‘OVERRIDE’?
   virtual void clone() const OVERRIDE  { }
                              ^~~~~~~~
                              OVERRIDE


The reason for it is an ordering issue:

class DocTargetDriver {
  virtual void clone() const OVERRIDE  { }
};
#define OVERRIDE override


I am not sure how to best resolve it. Filtering out would be simple (input and
output are identical); however, I wonder whether it makes more sense to
explicitly point out the ordering issue.
