This would need another hunk, too ... :( see [1]. otherwise, the limit is too
low (the minimum), and it won't work with a reasonable big environment.

I'd be more for 2, as i'm currently contaminating a whole lot of packages with
suacomp anyway (gnulib, coreutils, etc.).
However, i'd be ok with 1 (+ the additional patch) too, whatever suits
findutils better...

Thanks for taking the time :) Markus
