            Bug ID: 89534
           Summary: mingw is not declarting MAKE_DECL_ONE_ONLY macro
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
  Target Milestone: ---

I'm curious why the target is not using

#define MAKE_DECL_ONE_ONLY(DECL) (DECL_WEAK (DECL) = 1)

is it intentional or a missing feature?
