Summary: non-pointer to pointer cast (bug?)

Initial Comment:
~/src/test $ cat ptrass.c 
int main(void) {

  int *x;
  int y;
  
  x = (int *) y;
/* x = *(int **) &y seems to work */

return 0;
}

~/src/test $ sdcc ptrass.c 
ptrass.c:6: error: non-pointer type cast to generic pointer
from type 'int'
to type 'int generic * '
ptrass.c:8: error: code not generated for 'main' due to
previous errors

SDCC can't fill in anything usefull for the memory region of 
the generic pointer. Therefore it's impossible to cast anything 
but 0 to a generic pointer.
Hint: you can cast to e.g. (int xdata *).
