Not building on Ruby 3.0.7: incompatible pointer type [-Wincompatible-pointer-types] #801
Description
It appears Redcarpet is no longer building on GitHub Actions with the latest ruby/setup-ruby@v1 on Windows, I'm not sure what's changed:
> gem install sass activesupport chunky_png md_to_bbcode nokogiri
Run gem install sass activesupport chunky_png md_to_bbcode nokogiri
ERROR: Error installing md_to_bbcode:
ERROR: Failed to build gem native extension.
