I was using C++17. I did try C++14 just to make sure but the issue is
there with both versions. I've noticed with my new MSVC 2022 that it
only goes down to 14, so I could not test 11.

I've chopped down the grammar file to it's bare minimum.
I have attached the grammar file and the generated files to this email

If the skeleton is glr.cc then the grammar compiles without errors.
With glr2.cc I get the following errors:
