Portability problems fixed by Gnulib:
@itemize
+@item
+On Windows platforms (excluding Cygwin), the descriptors returned by
+the @code{socket} function cannot be used in calls to @code{read},
+@code{write}, and @code{close}; you have to use @code{recv}, @code{send},
+@code{closesocket} in these cases instead.
+@item
+On Windows platforms (excluding Cygwin), error codes for @code{socket}
+are not placed in @code{errno}, and @code{WSAGetLastError} must be
+used instead.
