/* Support files for GNU libc.  Files in the C namespace go here.

   Files in the system namespace (ie those that start with an underscore)
3
   go in syscalls.c.

5
   Note: These functions are in a seperate file so that OS providers can
6
   overrride the system call stubs (defined in syscalls.c) without having
7
   to provide libc funcitons as well.  */
