problem regarding kernel 2.4.18 and grsecurity 1.9.4 (in woody)

[smurfd <smurfd@phreaker.net>]

Hey folks, im not sure if this is a bug or if im doing something wrong.

Ive been having problems compiling the 2.4.18 kernel with the grsecurity
1.9.4 patch applied. Seems that it had something to do with the ACL
option that grsecurity offers.

Has someone had the same problem, and is there any solutions..
(oh yeah, its on a old pentium 100, but that cant be any problem...)
here is the end of my kernel compiling 

---- start ------

I would be glad if anyone can help me, and then this might stop others
from getting in the same situation as me.
