 Portability problems not fixed by Gnulib:

-This function will not replace a destination that is currently opened
+@item
+POSIX requires that @code{rename("symlink-to-dir/","dir2")} rename
+@file{dir} and leave @file{symlink-to-dir} dangling; likewise, it
+requires that @code{rename("dir","dangling/")} rename @file{dir} so
+that @file{dangling} is no longer a dangling symlink.  This behavior
+is counter-intuitive, so on some systems, @code{rename} fails with
+@code{ENOTDIR} if either argument is a symlink with a trailing slash:
+glibc, OpenBSD, Cygwin 1.7.
+@item
+This function will not rename a source that is currently opened
 by any process:
