Sorry, I forgot about bug 727 (http://bts.frama-c.com/view.php?id=727)
which is solved in svn, but not in the current release: in Carbon,
current_func is not properly set when inspecting a specification. You
can use self#current_kf instead (which gives you a
Db_types.kernel_function, in fact current_kf should be preferred over
current_func, as a kernel_function contains more information than a
fundec). Note however that current_kf is set also when you're visiting
the specification of a leaf function (prototype without corresponding
implementation). You can discriminate prototypes and definition with
Kernel_function.is_definition.

For what it's worth, the patch against Carbon release that fixes issue
727 is included in this mail.
