Malloc does return void *.  You just need to include <stdlib.h> to properly
define it (C treats all calls to functions that haven't been defined yet as
returning int).  This would be apparent on some 64-bit systems (because int is
only 32-bits on those systems) or on some 68k systems (where ints are returned
in d0 and pointers are returned in a0).
