linux-2.3.99-pre10-1 no longer defines struct user_i387_struct,
but i387_hard_to_user and i387_user_to_hard still reference it. I
believe this patch should fix the problem.
By the way, the compile problem was apparently a side
effect of some changes that appear to support some kind of faster
floating point context saving and restoring. I am not complaining
about harmless ifdef'ed processor optimizations, but I would like to
point out that it would be nice to be able to have a kernel that
could run on a 386 (and therefore can be the default in a distribution)
and yet could take advantage of these features when run on a 686 without
having to expend so many cycles on detecting this as to lose the
optimization.
