Portability problems fixed by Gnulib:

  * This header file is missing on some platforms: mingw.

  * This header file is not self-contained on some platforms: it requires <sys/types.h> to be included first.

  * This header file is lacking the SHUT_RD, SHUT_WR, SHUT_RDWR macros on some platforms, despite having the shutdown functions: emx+gcc.

  * The struct sockaddr_storage type does not have a member ss_family on some platforms: AIX 7.1.
