/*
 * 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.
