Right, but those are your system headers. We didn't ship them. They're bundled
with your distribution!

Not at all.

When I diff lib/urldata.h between 7.56.1 and 7.57.0, I can't see any
difference in includes in that either. And configure checks if it can include
netinet/in.h and defines HAVE_NETINET_IN_H accordingly so there's clearly
something weird going on there that makes it fail in this particular
instance...

Can you figure it out?
