  * This function is missing on many non-glibc platforms: MacOS X 10.5, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, Interix 3.5, BeOS.

Portability problems not fixed by Gnulib:

Other problems of this function:

  * There is an inherent race between calling this function and performing some action based on the results; you should think twice before trusting this function, especially in a set-uid or set-gid program.

  * This function does not have an option for not following symbolic links (like stat versus lstat).  If you need this option, use the Gnulib module faccessat with the AT_EACCESS flag.
