Portability problems fixed by Gnulib:

  * This function is missing on some platforms: glibc 2.16, OS X 10.8, FreeBSD 9.1, NetBSD 6.0.1, OpenBSD 5.2, Minix 3.2.0, AIX 7.1, HP-UX 11, IRIX 6.5, Solaris 11, Cygwin, mingw, MSVC 9, Interix 6.1, BeOS.

Portability problems not fixed by Gnulib:

  * On platforms other than glibc 2.0 and later, the Gnulib replacement function always returns a null pointer, even when invoked in a non-setuid program.
