If that would be of any help, I use these routines to figure out include paths (GCC must be installed and properly configured): ```lisp (ql:quickload :claw) (claw::dump-all-gcc-include-paths) (claw::dump-all-darwin-framework-paths) ```

Does `cffi` load? ```lisp ;; Evaluate after clean restart (ql:quickload :cffi) ```

This is [cffi](https://github.com/cffi/cffi) issue then. But just in case, ensure you don't have anything in ~/quicklisp/local-projects directory, nuke caches (probably in ~/.cache/common-lisp/), then do ```lisp (ql:update-all-dists) ``` And try again.

I'm not planning to maintain this PR too. Feel free to close it.

Added `:local-os` option into this PR. Allows to force specific os into triplet. This is to resolve `-msvc` vs `-gnu` environment we discussed today.

I don't plan to maintain this PR any further. Feel free to close it.

Yeah, quickloading on Windows hangs for a while - I'm not sure why. Try leaving it for 30min or smth.
