help with different treatment of asms in 3.2 and 3.3?

[Brad Lucier]

3.2 compiles the following code without complaint (beyond the warnings)
and 3.3 rejects it.  The code is from the MLton ML compiler runtime; I
know nothing about inline asms; could someone offer some advice?

int Int_quot(int numerator, int denominator) {
        register int eax asm("eax");

        eax = numerator ;

        __asm__ __volatile__ ("cdq\n        idivl %1"
                :
                : "r" (eax), "m" (denominator)
                : "eax", "edx");

        return eax;
}
