It might be an idea to merge across the lib/replace/repdir/
replacements for opendir and related calls from Samba4 to Samba3 to
fix this. The BSD ones are too broken to use, and it seems simplest to
just replace them on the broken systems.

See also the autoconf test in lib/replace/repdir/config.m4
