1998-10-29  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/ttyname_r.c (ttyname_r): Try reading
	/prof/self/fd/FD first.
	* sysdeps/unix/sysv/linux/ttyname.c (ttyname): Likewise.

	* stdio-common/_itoa.h (_fitoa_word): New inline function.  Write
	formatted number starting at given position and return pointer to
	following byte.
	(_fitoa): Likewise, for long long.
