This function ignores trailing slashes on symlinks on some platforms,
such that @code{renameat(fd,"link/",fd,"new")} corrupts @file{link}:

This function is declared in @code{<unistd.h>} instead of @code{<stdio.h>}
on some platforms:

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
+glibc 2.3.6, MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, AIX
5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 8, 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.
