 Gnulib module: rename
 
 Portability problems fixed by Gnulib:
 @itemize
 @item
-This function does not work when the source file name ends in a slash on
-some platforms:
+This function does not allow trailing slashes when creating a
+destination directory, as in @code{rename("dir","new/")}:
+NetBSD 1.6.
+@item
+This function does not reject trailing slashes on the destination for
+non-directories on some platforms, as in @code{rename("file","new/")}:
+AIX 7.1, Solaris 11 2011-11, Cygwin 1.5.x, mingw, MSVC 9.
+@item
+This function does not reject trailing slashes on symlinks to
+non-directories on some platforms, as in
+@code{rename("link-to-file/","f")}:
+FreeBSD 7.2.
+@item
+This function ignores trailing slashes on symlinks on some platforms,
+such that @code{rename("link/","new")} corrupts @file{link}:
+Solaris 9.
+@item
+This function incorrectly reduces the link count when comparing two
+spellings of a hard link on some platforms:
+NetBSD 1.6, Cygwin 1.5.x.
+@item
+This function will not always replace an existing destination on some
+platforms:
+Cygwin 1.5.x, mingw, MSVC 9.
+However, the replacement is not atomic for directories, and may end up
+losing the empty destination if the source could not be renamed.
+@item
+This function mistakenly allows names ending in @samp{.} or @samp{..}
+on some platforms:
+Cygwin 1.5.x, mingw, MSVC 9.
+@item
+This function does not reject attempts to rename existing directories
+and non-directories onto one another on some platforms:
+Cygwin 1.5.x, mingw, MSVC 9.
+@item
+This function does not allow trailing slashes on source directories on
+older platforms, as in @samp{rename("dir/","new")}:
 SunOS 4.1.

 Portability problems not fixed by Gnulib:
 @itemize
+@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
+After renaming a non-empty directory over an existing empty directory,
+the old directory name is still visible through the @code{stat} function
+for 30 seconds after the rename, on NFS file systems, on some platforms:
+Linux 2.6.18.
+@item
+This function will not rename a source that is currently opened
+by any process:
+mingw, MSVC 9.
