  Gnulib module: getopt-gnu
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  AIX 5.1, HP-UX 11, IRIX 6.5, MSVC 14.
  @item
  The function @code{getopt_long} does not obey the combination of
  @samp{+} and @samp{:} flags in the options string on some platforms:
  glibc 2.11.
  @item
  The use of @samp{W;} in the optstring argument to does not always
  allow @code{-W foo} to behave synonymously with @code{--foo}:
  glibc 2.11.
  @item
  The function @code{getopt_long} does not support the @samp{+} flag in
  the options string on some platforms:
  macOS 11.1, AIX 5.2, Solaris 10.
  @item
  The value of @code{optind} after a missing required argument is wrong
  on some platforms:
  macOS 11.1.
  @item
  The function @code{getopt_long} does not obey the @samp{-} flag in the
  options string when @env{POSIXLY_CORRECT} is set on some platforms:
  Cygwin 1.7.0.
  @item
  Some implementations fail to reset state, including re-checking
  @env{POSIXLY_CORRECT}, when @code{optind} is set to @samp{0}:
  NetBSD, Cygwin 1.7.0.
  @item
  The function @code{getopt_long} does not support options with optional
  arguments on some platforms:
  macOS 11.1, OpenBSD 4.0, AIX 5.2, IRIX 6.5, Solaris 11 2010-11, Cygwin 1.5.x.
  @item
  This function crashes if the option string includes @code{W;} but
  there are no long options, on some platforms:
  glibc 2.14.
