I found a problem in gdb-4.5 on systems where integers and
pointers are NOT the same size.

(gdb) p (void*) 5
Invalid cast.
(gdb) p (void*) 500000
$1 = (void *) 0x7a120
(gdb) p (void*) (long) 5
$2 = (void *) 0x5
(gdb) 

A possible fix is the following : at the end of value_cast function
(in valops.c) do :

    {
	/* Always accept a cast of an integer into a pointer,
    even when the sizes are not equals !
	 */
      if (code1 == TYPE_CODE_PTR && scalar)
		return value_from_longest (type, value_as_pointer (arg2));	

      error ("Invalid cast.");
      return 0;
    }

Important: I also noticed that in value_cast(), in case pointers
and integers are the SAME size, value_as_pointer() is NOT called
to transform the value into a pointer, which is NOT very clean...

Let me know your comments.
