When jextract makes downcall to clang_reparseTranslationUnit_Impl it sets up the third parameter in the struct incorrectly. It sets INT instead of LONG so on big endian platform the parameter will be set differently.

The latest version passes all tests on my Windows machine.

Could you please update the README at https://github.com/openjdk/jextract/tree/master/updateclang to reflect the changes that were needed to `CXUnsavedFile`? You can include the patch that I sent in that file.

Other than that, this looks ready to me.
