Re: NEC-LIST: Unix NEC or C port?

It would have to have been more than 4 years ago, and I don't recall where I
saw it. It might have been someone who took the f2c output and
reformatted/reedited it. I remember looking at a few of the modules
(because I needed some of the functions) and it wasn't totally unreadable.
