Sorry for reviving such an old thread... :)

i never got an answer on the last mail, and i just saw, that there is still 
some quirks going on in my findutils-4.5.9 ebuild regarding this issue.

Since i fixed sysconf() for interix through [1], it'd be neccessary to revert 
[2] in the findutils git repo. Is that ok for you? Doing so will require 
libsuacomp when building findutils. nothing has to be done on the findutils 
side though, as suacomp installs itself as libc.{a,so}, and thus gets in
