           Summary: -Wold-style-definition incorrectly warns with
                    ellipsises.
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: kcook at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

In attempting to compile GCC with -Wold-style-definition, I ran into many of the
following errors, which are false positives due to the ellipsis.

From gengtype.c:70

/* Wrapper for xvasprintf.  */
char *
xasprintf (const char *format, ...)
{
  char *result;
  va_list ap;

  va_start (ap, format);
  xvasprintf (&result, format, ap);
  va_end (ap);
  return result;
}

This warns with:

../../gcc-snapshot/gcc/gengtype.c: In function `xasprintf':
../../gcc-snapshot/gcc/gengtype.c:73: warning: old-style parameter declaration

Reduced Testcase and suggested patch coming shortly
