  Gnulib module: sys_socket
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This header file is missing on some platforms:
  mingw, MSVC 14.
  @item
  This header file is not self-contained on some platforms: it requires
  @code{<sys/types.h>} to be included first.
  @item
  This header file does not define the type @code{socklen_t} on some platforms:
  HP-UX 10.20, IRIX 6.5, OSF/1 4.0, Interix 3.5, BeOS.
  @item
  This header file does not define the type @code{struct iovec} on some platforms:
  OpenBSD 4.4.
  @item
  This header file is lacking the @code{SHUT_RD}, @code{SHUT_WR},
  @code{SHUT_RDWR} macros on some platforms, despite having the @code{shutdown}
  functions:
  emx+gcc.
  @item
  The @code{struct sockaddr_storage} type does not have a member @code{ss_family}
  on some platforms:
  AIX 7.1.
  @item
  The @code{CMSG_SPACE} and @code{CMSG_LEN} macros are not provided on some
  platforms:
  OpenVMS.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This header file does not declare the @code{msg_control} and
  @code{msg_controllen} members of @code{struct msghdr} on some
  platforms.  This can be detected by the absence of the
  @code{CMSG_FIRSTHDR} macro:
  gnulib replacement header, old BSD
  @end itemize
