            Bug ID: 67479
           Summary: Support for -Wformat-pedantic
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mark at gcc dot gnu.org
  Target Milestone: ---

Currently to get pedantic format warning, like for the usage of deprecated old
'Z', 'q', etc gnu_printf modifiers, you need to give both -Wpedantic and
-Wformat. But this enables also non-format specific pedantic warnings.

It would be nice to -Wformat-pedantic to just get the format related warnings
(or maybe a -Wformat-deprecated just for warning about the deprecated
gnu_printf modifiers).
