2010-11-01  Nicola Pero  <nicola.pero@meta-innovation.com>

        Implemented format and noreturn attributes for Objective-C methods.
        * c-common.c (handle_noreturn_attribute): Recognize 'noreturn'
        attribute for Objective-C methods.

In gcc/objc/:
2010-11-01  Nicola Pero  <nicola.pero@meta-innovation.com>

        Implemented format and noreturn attributes for Objective-C methods.
        * objc-act.c (objc_start_method_definition): If method attributes
        are specified emit a warning and ignore them.
        (build_objc_method_call): Moved deprecation warnings from here ...
        (objc_finish_message_expr): to here.  Do not emit deprecation
        warnings if the receiver is of type 'id'.
        (really_start_method): Install 'deprecation' and 'noreturn'
        attributes.
        (objc_decl_method_attributes): Carefully filter out the list of
        attributes, allowing only "noreturn", "format", "sentinel" and
        "deprecated".  In the case of "format", adjust the arguments.
        Always process the attributes in the same way no matter if
        "sentinel" is in the list or not.
