And?..

You are the author, not me. You know your code much better and
it will be quite easy to perform. I may miss things, but reading
briefly the 1000 lines and get what headers are required takes
no more than half an hour.

(Tools that help me, in case I don't remember by heart, are
 `cscope` and `git grep ...`.)

LGTM.
