            Bug ID: 66918
           Summary: Disable "inline function declared but never defined"
                    warning
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: eugene.zelenko at gmail dot com
  Target Milestone: ---

It looks like there is no way to disable this warning (at least in 5.2.0).

Part of my code base is built with -Werror, so I usually treat warnings
introduced in new versions of GCC as no errors (-Wno-error). "inline function
declared but never defined" point to -Werror as way to disable it, but I think
will be better to have individual switch.
