From 217e398585984539142aca07b977915968cb9593 Mon Sep 17 00:00:00 2001
From: Joel Sherrill <joel.sherrill@OARcorp.com>

Subject: Modified fstat and stat to be consistent with isatty in that all
 three now pretend that everything is a tty.  This insures that newlib makes
 the console output line buffered.
