[PATCH] Build failure - missing linux/limits.h include?

No, don't include kernel headers directly if you can avoid it.
The problem you are referring to seems to be with old tool chains,
I have the same symptom with my s390 gcc-2.95/glibc-2.1.3.
Including <sys/param.h> instead of <limits.h> seems to fix it.
