----------------------------------------
This is a followup of #15391 which fixes JIT to respect the configuration options. However, I still wonder, why the file is versioned and why it is not stored in the versioned directory alongside all other internal Ruby headers. I believe, that while it now respects the header configuration flags, it still does not respect options such as "--with-ruby-version"
