You should hardly be worrying about spinlock performance when you are
using that toy non-optimizing compiler. Get a real compiler --- either
gcc or HP's extra-money compiler ...
Aside from being free, gcc has the advantage that the spinlock code
should work out-of-the-box. I don't think anyone's built a solution
for HP's compiler on IA64 yet.
