My 2.4.20-benh didn't compile with 3.3 so I tried another approach:
Changed the spinlock_t and SPIN_LOCK_UNLOCKED definitions to match those
for gcc <= 2.95 even when compiling with gcc 3.3. Built the mol modules
using 3.3 and mol runs fine now. That's a brute force hack, sure, but it
might help people with kernels built using gcc 2.95.
(I don't suggest putting that into the mol modules source, just for the
record.)
