 Portability problems fixed by Gnulib:
 @itemize
+@item
+This function is missing on some platforms:
+mingw, MSVC 9.
+@item
+This function fails to reject trailing slashes on non-directories on
+some platforms:
+FreeBSD 7.2, Solaris 11 2011-11, Cygwin 1.5.x.
+@item
+When the second argument is a dangling symlink, some platforms follow
+that link and create the destination rather than failing:
+IRIX 6.5.

 Portability problems not fixed by Gnulib:
 @itemize
 @item
-This function is missing on some platforms:
-mingw.
+When the first argument is a symlink, some platforms create a
+hard-link to what the symlink referenced, rather than to the symlink
+itself.  Use @samp{linkat} to force a particular behavior.
