* \brief Tell SDL not to name threads on Windows.

* The variable can be set to the following values:
* "0" - SDL will raise the 0x406D1388 Exception to name threads.
* This is the default behavior of SDL <= 2.0.4. (default)
* "1" - SDL will not raise this exception, and threads will be unnamed.
* For .NET languages this is required when running under a debugger.
