 * Only EDOM and ERANGE are required by ANSI/ISO 9899-1990.
 * Other values defined here are required by Posix.1
 * (ISO/IEC 9945-1:1990, a.k.a. IEEE 1003.1-1990), except:
 * ENOTBLK and ETXTBSY are defined here but not in Posix.1, and
 * EDEADLK, ENOLCK, ENOTEMPTY, ENOSYS are in Posix.1.
 * Error number values 1-34 are fairly standard across different hosts,
 * while values 35 and up vary widely.
