I don't have 3.3 but I tried it on 3.2.2 and the behavior persists.
Interestingly, with 3.2.2, it's the -DFAST code that runs more slowly.
Here's a trace:

$ gcc --version|sed 1q
gcc (GCC) 3.2.2
$ gcc t.c ; time ./a.out

real    0m0.724s
user    0m0.710s
sys     0m0.000s
$ gcc -DFAST t.c ; time ./a.out

real    0m2.020s
user    0m2.020s
sys     0m0.000s
