This was detected by a warning on the upcoming SBCL 2.0.7. This causes cascading errors in other systems which depend on this one http://report.quicklisp.org/2020-07-24/failure-report/cl-sdl2-ttf.html#sdl2-ttf

This breaks a ton of stuff if left unmerged.

Just wanted to fix this myself only to discover this PR sent 2 years ago :(

Don't worry. I'm sure it'll get merged in another five or six
