I think you misunderstood.  The test scripts produced by autoconf won't 
necessarily work on Windows, but it's still worth trying.  Just extract 
the tests for SSE2 and inttypes.h from your script on some other 
platform, and adapt them to Windows.  They can probably be shortened, 
because there's less variability.

You can count on Windows using gcc 4.x for current and future versions, 
probably until 5.x becomes commonly used.  I don't know if inttypes.h is 
guaranteed in all of those, but it is currently present.
