/* Don't trace faults under OSF/1, rely on the posting of the appropriate

   signal if fault tracing is disabled.

   Tracing T_IFAULT under Alpha OSF/1 causes a `floating point enable'

   fault from which we cannot continue (except by disabling the

   tracing).

   And as OSF/1 doesn't provide the standard fault definitions, the

   mapping of faults to appropriate signals in procfs_wait is difficult.  */
