The interesting thing about "portability libraries" is that they always seem to become replacement libcs.  See apr, nspr, ...

These will need to be looked at on a case-by-case basis.  Picking an item out of the list, evaluating it, and supplying a patch for it might be a good way for a newcomer to start contributing to groff.

I would not start with the very first item.  I don't think any program distributed with groff opens any sockets at any time for any reason.  ("Change my mind", as the meme goes, while I sip coffee.)
