I'm terribly sorry, but that won't work either. First of all, 
gcc 3.3.3 has no option --fno-strict-aliasing. The closest I
could find is --mno-strict-aliasing. Secondly, neither of those options
works. I tried various combinations of commands, and none of them works. 
Particularly interesting is the last error: undefined reference to
<predicate 'main'/2 mode 0>.

Here is the code I am trying to compile:

:- module main.

:- interface.

:- import_module io.

:- pred main(io__state, io__state).
:- mode main(di, uo) is det.

:- implementation.

	

main(IO, IO3):-
	io__print("ciao", IO, IO3).
