             Bug #: 51849
           Summary: -Wc99-compat would be considered useful
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: b...@gcc.gnu.org


The default "C" language dialect for GCC is gnu89. To ease the transition to
the eventual switch to gnu99, a warning flag is desired that can flag
potentially changed language features between C89 and C99, much like
-Wc++11-compat helps programmers transition from C++03 to C++11.
