getsockname tests: More tests.
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.
