 Portability problems fixed by Gnulib:
 @itemize
+@item
+Some platforms fail to detect trailing slash on non-directories, as in
+@code{fchown(dir,"link-to-file/",uid,gid,flag)}:
+Solaris 9.
+@item
+Some platforms mistakenly dereference symlinks when using
+@code{AT_SYMLINK_NOFOLLOW}:
+Linux kernel 2.6.17.
+@item
+This function is missing on some platforms:
+glibc 2.3.6, MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, AIX
+5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.5.x, mingw, Interix 3.5, BeOS.
+But the replacement function is not safe to be used in libraries and
+is not multithread-safe.  Also, the replacement may fail to change
+symlinks if @code{lchown} is unsupported, or fail altogether if
+@code{chown} is unsupported.
