See end of earlier thread here: https://lists.gnu.org/archive/html/bug-gnulib/2021-07/msg00070.html I'm not sure what could be done. Perhaps adding a sentence to the gnulib documentation stating that the gnulib fts is not a drop-in replacement for missing fts functionality but a separate implementation with different behaviour. /Simon
