The multi-single.c example on http://curl.haxx.se/libcurl/c/multi-single.html always causes select() to fail with WSAGetLastError() returning error 10022 (Winsock invalid argument)

I am using Visual Studio 2005, Windows XP SP3, libcurl version 7.19.3.

Please don't use 7.19.3, upgrade!

Does anyone have any idea why, or how to make it work?

I guess this happens because max_fd contains -1 in that moment and that's just plain wrong to call select() at that point. The example should be fixed to not do that...
