Okay, I will try this later.

Sorry, I wasn't clear.  You're refering to the same file that I looked 
at.  These are the enum's provided:

/* These values are the indices for the standard per-thread variables.  */
enum __hurd_threadvar_index
  {
    _HURD_THREADVAR_MIG_REPLY,  /* Reply port for MiG user stub 
functions.  */
    _HURD_THREADVAR_ERRNO,      /* `errno' value for this thread.  */
    _HURD_THREADVAR_SIGSTATE,   /* This thread's `struct hurd_sigstate'.  */
    _HURD_THREADVAR_DYNAMIC_USER, /* Dynamically-assigned user variables. */
    _HURD_THREADVAR_MALLOC,     /* For use of malloc. */
    _HURD_THREADVAR_DL_ERROR,   /* For use of -ldl and dynamic linker. */
    _HURD_THREADVAR_MAX         /* Default value for 
__hurd_threadvar_max.  */
  };

This file in my libc checkout hasn't been updated since 1999.  Have I 
missed a commit somewhere?
