 In WarnLevel.c, in CCTK_VWarn (called by CCTK_Warn), it says

  if (level <= error_level)
  {
    CCTK_Abort (NULL, 0);
  }

 The second argument to CCTK_Abort is the exit code of the process.  So if
 there is an "error" warning, the process exits with 0 exit code; i.e.
 success!  This happens in several places in this file.

 The user guide does not say anything about the exit code of Cactus.  I
 think that if Cactus has a level-0 warning, i.e. an error, then it should
 exit with a non-zero exit code, and Erik agrees.
