In particular, the former is rather problematic since it breaks compilation as the Visual C++ becomes stricter and more compliant with every release, which means the way Windows code treats long as a typedef for int is no longer correct, especially with -permissive- enabled. Instead of changing every piece of broken code to match the jint = long typedef, which is far too time consuming, we can instead change jint to an int (which is still the same 32 bit number type as long), as there are far fewer problems caused by this definition. It's better to get this over and done with sooner than later when a future version of Visual C++ finally starts to break on existing code

While looking through the code for this I've come to realize that a staggering amount of code in the accessibility binaries specify longs where unsigned longs would be much more appropriate (see the one example in this PR for instance), wonder if this should also be fixed in the long term too
