Gnulib documents most portability quirks too [1]. For example, it had the FreeBSD EMLINK and NetBSD EFTYPE with 'open("symlink", O_NOFOLLOW ...) documented, but for some very old versions released around 2014. Now that I have confirmed it still exists from this git test I have updated the documentation there [2].
