[PATCH] broken dd on systems without __fpending

[Mikulas Patocka]

Hi

There is a bug in dd --- if libc doesn't have __fpending, coreutils will 
use a stub that always returns 1. A side effect of this stub is that 
close_stdout always calls fclose(stdout) --- it normally doesn't matter 
for most utilities except dd --- dd calls close(1) on its own and later 
fclose(stdout) in atexit(close_stdout) will report error.

This patch fixes the problem by moving atexit(close_stdout) to usage() 
function --- its the only function in dd that uses stdout.
