It is the full VS2005 with the Platform SDK from a couple of months ago.

compile a simple source file which has the following lines, what do
you get ?

/*---8<-----8<-----8<-----8<-----8<--*/
#ifndef WIN32_LEAN_AND_MEAN
#define WIN32_LEAN_AND_MEAN
#endif
#include <windows.h>
#include <winsock2.h>
#include <ws2tcpip.h>
struct test1 {
  int a_i_1;
  socklen_t a_s_1;
};
/*---8<-----8<-----8<-----8<-----8<--*/

Mostly errors from winsock2.h -- I commented out ws2tcpip.h and the struct test and got the first 57 errors. I must be doing
something simple and stupid ...

I did not do the second test yet, since the errors are coming from the winsock2.h header file.

Do you have an idea of what is wrong?

Thanks,

Max
