gcc 4 and 3.3. The result with both is exactly the same.

I have a simple chunk of code which looks like:

     if (Q3Error_Get(nil) != kQ3ErrorNone) {
         ...
         return kQ3Failure;
     }


With d18 there's no error and all is well. With 1.7 however, this  
returns true (this is while reading a 3DMF file). I was pretty  
skeptical about there being anything actually wrong, so I did some  
investigating. I first tried:

     TQ3Error error = Q3Error_Get(nil);
     printf("%s", Q3Error_ToString(kQ3LanguageEnglishUS, error));
     if (error != kQ3ErrorNone) {
        ...
        return kQ3Failure;
     }


The result: "No error", yet when the != comparison is done, there  
*is* an error. So I dug a bit further:

     printf("Error: %i \n", error);


With gcc 4.0 I get:
     warning: format '%i' expects type 'int', but argument 2 has type  
'long long int'

My initial thought was that this was some gcc 4.0 incompatibility so  
I reverted to 3.3 and got:
     warning: int format, different type arg (arg 2)


However, with either version of gcc, if I use the framework I built  
for 1.6d18 it works just fine.
