Looking at rust's github page, I see discussions about > using readdir_r on Fuchsia and Linux, but nothing about BSD. If you look at these tickets, there are people pointing out that readdir_r() doesn't work correctly even on platforms where it isn't formally deprecated. The Rust developers chose to fix the Linux case because it produced a link-time warning and ignored the rest. That's on them. They also seem to be providing their own prototype for readdir_r(), which suppresses the deprecation warning they should be getting on FreeBSD 15, and turns the issue from a failure to compile into a failure to link. That's also on them. > possibly with the aid of installing misc/compat14x That won't make any difference since readdir_r() is still in our libc.
