           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal

         Component: other
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

it would save time for contributors if GCC could detect that you're building
inside the directory and ask you to cd to a different directory and build there
and refer to documentation for details
