Indeed.

Hi, new compiler versions are more strict with func functions. This is probably the reason why this project doesn't compile and emits the error above. You may just change: func -> proc for the two funcs: pastMinKey and pastMaxKey I also added a pull request that fixes the issue.

Fixed as part of #21.

(I’d prefer to leave these as func and fix the bug by making compareKey and mdbx_compare_key (sp?) funcs too, but it’s not a big deal.)
