They kind of work (with HiTech compilers PICC/PICC18), but they are limited
in their functionality. AFAIK, no two pointers may refer to functions with
the same "signature". 

This makes sense, as calculating a static call stack becomes practically
impossible if you allow normal function pointer functionality (with all the
"usual" tricks like casting integers to function pointers :)
