[C++ PATCH] Fix PR 16301, ICE with strong used

Another error recovery problem.

This patch has been in the bug for 3 months.  The reason why I had not
submitted until today is because I forgot about the patch and I did not
fully test it when I added it to the bug report.

OK? Bootstrapped and tested on powerpc-darwin with no regressions.

Thanks,
Andrew Pinski

ChangeLog:

	* namelookup.c (parse_using_directive): If we have a
	error_mark_node, do not set the decl namespace associations
	on it.

testsuite/ChangeLog:
	* g++.dg/lookup/strong-using-4.C: New test.
