Because it lets you have access to the 64bit arithmetic capabilities of the hardware, even when you don't need the 64bit addressing capabilities.

Hmm, good point. Actually, I think in IRIX n32 it was indeed "long long" that was 64bit! (Making 64bit long risked breaking software that assumed sizeof(long) == sizeof(void *) and tried to store longs in pointers).
