For ICC it seems to depend on the ICC version, newer ICC versions
report newer __GNUC_MINOR__.
That said, ICC doesn't error out on the LHS cast for -m32, just
silently drops the cast, so we really can't say it is compatible
in this regard.
unsigned long i;
void
foo (void)
{
asm volatile ("# %0 %1" : "=r" ((unsigned long long) i) : "0" ((unsigned long
long) 0));
}
