CGO causes a ton of errors of the form "int not declared by package C", for every type.
There's also one error that says "could not import C (cgo preprocesseing failed (go-staticcheck))
The logs file is with gopls trace logs turned on.
The logs were created right after I hit save. The file where CGO is used is this one:
