As it happens, I encountered your real problem quite recently. :)
"(int)(1<<31)" is undefined (C99 standard 6.5.7/4).
This modified version gives the same result both ways:
int main (){
unsigned long long a = 18446744065119617024llu;
/* results expected to be identical */
#ifdef EXPECTED
unsigned int b = ((unsigned int)(1<<31));
a = a / b;
#else
a = a / ((unsigned int)(1<<31));
#endif
return a;
}
