/* The m68k SVR4 ABI defines that pointers are returned in %a0 instead of

* %d0. So if a function pointer is declared to return a pointer, the

* compiler may look only into %a0, but if the called function was declared
|

* to return return an integer type, it puts its value only into %d0. So the

* caller doesn't pink up the correct return value. The solution is to
|
||||
* declare the function pointer to return int, so the compiler picks up the
|
||||
* return value from %d0. (Functions returning pointers put their value
|
||||
* *additionally* into %d0 for compability.) The price is that there are
