9 Portability problems fixed by Gnulib:
12 Some platforms fail to detect trailing slash on non-directories, as in
13 @code{fchown(dir,"link-to-file/",uid,gid,flag)}:
16 Some platforms mistakenly dereference symlinks when using
17 @code{AT_SYMLINK_NOFOLLOW}:
20 This function is missing on some platforms:
21 glibc 2.3.6, MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, AIX
22 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.5.x, mingw, Interix 3.5, BeOS.
23 But the replacement function is not safe to be used in libraries and
24 is not multithread-safe. Also, the replacement may fail to change
25 symlinks if @code{lchown} is unsupported, or fail altogether if
26 @code{chown} is unsupported.
