I'm coming in late to this discussion, but compilers are allowed to accept 
invalid code, and (with some exceptions) are allowed to compile such code 
without a peep.

A compiler is allowed to accept:

     int i;
     printf("%d %d %d\n",i++,i++,i++);

and even generate the output that you expected.  That doesn't mean the code 
was valid.
