This function is missing on some platforms:
OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11.23, IRIX 6.5, Solaris 9, Cygwin 1.5.x, mingw, MSVC 14, Android 4.4.
However, the replacement may fail with @code{ENOSYS} or @code{ENOENT} on
some platforms.

Note that when using this function to open the master side of a
pseudo-terminal, you still need platform dependent code to open the
corresponding slave side. The Gnulib module @code{openpty} provides
an easy-to-use API that does both at once.
