Oh, you wrote 2.6.23, not 2.6.32!

I'm using 2.6.27, so this should be working. I googled a bit, and
found this page: http://www.in-ulm.de/~mascheck/various/argmax/, which
indeed mentions ARG_MAX should be relative to the stack size in new
kernels. I increased my stack size with ulimit -s, and checked that
getconf ARG_MAX indeed grows with it. Still, distcheck still fails the
same way no matter how much I increase the value. The page says
limits.h still shows the old value though (which is true), so I guess
someone is checking that and not the dynamic value. Sounds like a bug
somewhere, not sure exactly where (my shell?).
