   4  * Huge Nasty Error Table
   5  *
   6  * Plan 9 uses error strings, Unix uses error numbers.  This table tries to
   7  * match UNIX strings and Plan 9 strings to unix error numbers.  It is used
   8  * to preload the dynamic error table which can also track user-specific error
   9  * strings.
