Winsock not working inside a DynamoRio windows client

Hi,

I was trying to use sockets inside a Windows client but the WSA initialization fails:

``` C
#include
#include

DR_EXPORT void dr_client_main(client_id_t id, int argc, const char *argv[])
{

dr_enable_console_printing();
WSADATA WsaDat;
int result = WSAStartup(MAKEWORD(2, 0), &WsaDat);
if (result == 0)
dr_printf("WSA Initializated\n");
else
dr_printf("WSAStartup failed with error: %d\n", result);
}
```

The output is always the same:

```
WSAStartup failed with error: 10107
```

That error code in [msdn](https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668%28v=vs.85%29.aspx):

```
WSASYSCALLFAILURE
10107
System call failure.
A system call that should never fail has failed. This is a generic error code, returned under various conditions.
Returned when a system call that should never fail does fail. For example, if a call to WaitForMultipleEvents fails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs.
Returned when a provider does not return SUCCESS and does not provide an extended error code. Can indicate a service provider implementation error.
```

It seems that the DR transparency is interfering with the `WSAStartup` function.

Could anyone check why is this happening?

Any help will be appreciated.
