Date: Thu, 09 Oct 2003 15:21:54 +0200 Message-ID: User-Agent: Gnus/5.1002 (Gnus v5.10.2) Emacs/21.3.50 (gnu/linux) MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I'm getting this warning when building 2.6.0-test[567] for ia64 with MODVERSIONS enabled. This is a bug in genksyms, it can't cope with some arguments of __typeof__. The following patch will fix that. Actually the argument of __typeof__ is an abstract declarator, but the genksyms parser has no production for that; decl_specifier_seq also matches some invalid constructs, but I don't think this is a problem in practice, since the compiler will reject them.
