+ * On Win32, we map three kinds of error codes:
+ * - GetLastError(): for Win32 functions
+ * - WSAGetLastError(): for Winsock functions
+ * - errno: for standard C library functions
+ * 
+ * GetLastError() and WSAGetLastError() return error codes in
+ * non-overlapping ranges, so their error codes (ERROR_* and
+ * WSAE*) can be mapped by the same function.  On the other hand,
+ * errno and GetLastError() have overlapping ranges, so we need
+ * to use a separate function to map errno.
+ *
+ * We do not check for WSAEINPROGRESS and WSAEINTR because we do not
+ * use blocking Winsock 1.1 calls.
+ *
+ * Except for the 'socket' call, we do not check for WSAEINITIALISED.
+ * It is assumed that if Winsock is not initialized, that fact will
+ * be detected at the time we create new sockets.
