  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, mingw, MSVC 9, Interix 3.5, BeOS.
  @item
  On some platforms, this function fails to detect invalid fds with
  EBADF, but only if they lie beyond the current maximum open fd:
  FreeBSD 8.2.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  When the @var{sigmask} argument is nonnull on platforms that do not
  natively support this function, race conditions are possible when its
  gnulib implementation temporarily modifies the signal mask, and the
  behavior is unspecified in a multi-threaded process.
  @end itemize
