  71  * ANSI C defines EDOM and ERANGE.  POSIX defines the remaining values.
  72  * We may at some stage want to surround the extra values with
  73  * #ifdef _POSIX_SOURCE.
  74  * By an extraordinary coincidence, nearly all the values defined here
  75  * correspond exactly to those in OSF/1 and in Linux.  Imagine that.
  76  * The exception is ETIMEDOUT, which has different values in the two
  77  * systems.  We use the OSF/1 value here.
