 Hm... I'm not Klaus Klein, but yes, for m68kelf (at least), C functions
 return pointers returned in A0 (possibly in addition to D0).
 
 Whether to enforce this at the syscall interface or at the libc
 interface is probably a matter of taste, and your way we can't
 forget it.
 
 Uh... don't forget syscall_fancy (in addition to syscall_plain).
