            Bug ID: 94572
           Summary: Expunge references to direct-declarator
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mpolacek at gcc dot gnu.org
  Target Milestone: ---

The direct-declarator production was removed in CWG 681 but we still have many
references to it in the codebase.  This makes it harder to navigate.
