  Gnulib module: pipe2
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on many non-glibc platforms:
  glibc 2.8, macOS 11.1, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 11.3, Cygwin 1.7.1, mingw, MSVC 14, Android 2.2.
  But the replacement function is not atomic; this matters in multi-threaded
  programs that spawn child processes.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function crashes rather than failing with @code{EMFILE} if no
  resources are left on some platforms:
  Cygwin 1.7.9.
  @end itemize
  
  Note: This function portably supports the @code{O_NONBLOCK} flag only if the
  gnulib module @code{nonblocking} is also used.
