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