  *wchar_t *wcsncat(front, back, count) - append count chars of back onto front
  *
  *Purpose:
  *	Appends at most count characters of the string back onto the
  *	end of front, and ALWAYS terminates with a null character.
  *	If count is greater than the length of back, the length of back
  *	is used instead.  (Unlike wcsncpy, this routine does not pad out
  *	to count characters).
  *
  *Entry:
  *	wchar_t *front - string to append onto
  *	wchar_t *back - string to append
  *	size_t count - count of max characters to append
  *
  *Exit:
  *	returns a pointer to string appended onto (front).
  *
  *Uses:

  *Exceptions:
