  Gnulib module: getsockopt
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), error codes from this function
  are not placed in @code{errno}, and @code{WSAGetLastError} must be used
  instead.
  @item
  On HP-UX 11, in 64-bit mode, when the macro @code{_HPUX_ALT_XOPEN_SOCKET_API}
  is not defined, this function behaves incorrectly because it is declared
  to take a pointer to a 64-bit wide @code{socklen_t} entity but in fact
  considers it as a pointer to a 32-bit wide @code{unsigned int} entity.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Some platforms don't have a @code{socklen_t} type; in this case this function's
  fifth argument type is @samp{int *}.
  @item
  Many socket options are not available on all platforms.
  @end itemize
