There is no such tool called "C99-to-C89 converter and wrapper for ffmpeg".

That is a "C99-to-C89 converter and wrapper", but it is not specific to
ffmpeg (or any other project). The tool was originally developed there, and
has since moved to github.com/libav.

Derek is correct, I've simply been lazy. I just deleted it to prevent any

I know that the tool is also available at

You seem to be fine depending on, say, gcc or yasm, even though you don't
have total control over these. So I'm going to assume that your concerns
are mildly overstated and that you'll be fine.

Derek already gave you the correct location for the binaries. No, I don't
maintain the code in my personal repository anymore.

Me, Derek and Martin maintain the tool. Anyone is welcome to contribute.
Given that it's free software, there's nothing I can do to stop you from
forking the tool and putting it under someone else's maintainership, as
long as you abide by the original license under which the sources were
released by its owners.
