That's strange, scripts/headers_check.pl only exits with non-zero if it 
finds that a included header file is not exported:

			printf STDERR "$filename:$lineno: included file '$inc' is not 
exported\n";
			$ret = 1;

in all other cases the $ret assignment is commented out:

		# Warn until headers are all fixed
		#$ret = 1;

and it works for me on both v3.0-rc7 and next-20110707.
