For future reference, this kind of warning shows up with gcc-4.2 as
well, but not with
gcc-4.3 or higher. I think in this case, both gcc and sparse fail to
provide helpful
feedback, but the code is probably better done using either a typedef
for the function
type, or with a structure containing the function pointer.

Yeah, this is correct. I do not see the same warn while using gcc-4.8.
