+@item
+This function mishandles trailing slash on some platforms:
+FreeBSD 7.2, Solaris 9.
+@item

 Portability problems not fixed by Gnulib:
 @itemize
 @item
-This function is missing on some platforms:
-mingw.
+Use of this function for anything except fifos is not portable,
+generally requiring super-user privileges and knowledge of supported
+device numbers.
+@item
+If the argument exists and is a directory, this function fails with
+@code{EISDIR} instead of the correct @code{EEXIST}:
+HP-UX 11.11.
