[PATCH] Kill 4 warnings

[Jakub Jelinek <jakub@redhat.com>]

Hi!

Following patch fixes these warnings:

../iconv/skeleton.c:412: warning: unused variable `set'
tst-eof.c:19: warning: unused variable `tm'
tst-eof.c:18: warning: unused variable `ch'
Examples/ex9.c:35: warning: unused variable `th'

BTW: Shouldn't the linuxthreads testcases use test skeleton too, so that
if they hang (which is far more likely than in non-threaded tests) they
will be killed after timeout?

	* libio/tst-eof.c (do_test): Remove unused ch and tm variables.
	* iconvdata/iso-2022-jp-3.c (EMIT_SHIFT_TO_INIT): Kill warnings if
	-DNDEBUG.

	* Examples/ex9.c (main): Remove unused th variable.
