+Some platforms fail to detect trailing slash on non-directories, as in

+Some platforms mistakenly dereference symlinks when using

 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.
