 Er,
 After realising that this source came from NetBSD, I checked their CVS 
 repo, and found it already fixed there with an equivalent patch.
 
 There's also an equivalent in the kernel: 
 /usr/src/sys/alpha/alpha/divrem.m4. The kernel case might be a security 
 issue if you could find a syscall that would do arbitrary (assuming not 
 by zero!) division of 64-bit values.
