            Bug ID: 93252
           Summary: Warning for symbols that could be internalized
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: trass3r at gmail dot com
  Target Milestone: ---

Similar to -Wsuggest-final it would be nice to have a warning that identifies
functions that could be marked static (resp. anonymous namespaces for classes
in C++).
