I got

The problem is the testcase assumes the objc header files are installed
which is not always true. The following patch fixes it. If I don't hear
any objections by tomorrow, I will check it in as an obvious fix.

Thanks.

	* objc.dg/special/special.exp: Add -I${srcdir}/../../libobjc
	for header files.
