Not quite sure if they are related to -Wsystem-headers. Perhaps
-Wno-system-headers could be used for these files...

from gcc.dg/wtr-int-type-1.c:
/* Test for -Wtraditional warnings on integer constant types.
   Note, gcc should omit these warnings in system header files.
   By Kaveh R. Ghazi <ghazi@caip.rutgers.edu> 8/22/2000.  */
/* { dg-do compile } */
/* { dg-options "-Wtraditional" } */


from gcc.dg/cpp/syshdr.c:
/* Test for proper suppression of warnings in system headers,
   and only in system headers.  */
/* FRAGILITY WARNING: The only way we have to distinguish the good error
   from the bad error is that the good error is on line 4 and the bad is
   on line 5 (of their respective files).  dg.exp doesn't have any way to
   condition error matchers on the file they're in.  */
