BTW: Only three warnings during the compile of this kernel!

These warnings as the same as those resulting from building
2.5.73 with gcc-2.95, i.e., they are the result of gcc miscompiling
the empty structs that spinlocks reduce to on UP.
It's interesting to note that your Mandrake gcc-2.96 has this bug,
which previously was thought to be limited to gcc-2.95 and older.
Anyway, the fix is to revert patch-2.5.73's change to linux/spinlock.h.
The latest 2.5.73-bk includes the fix, or apply the patch below.

Thanks for the patch. Sorry for the repost.
