/* ANSI C namespace clean utility typedefs */

/* This file defines various typedefs needed by the system calls that support
   the C library.  Basically, they're just the POSIX versions with an '_'
   prepended.  This file lives in the `sys' directory so targets can provide
   their own if desired (or they can put target dependant conditionals here).
