It's amazing what will still compile and run. Consider this old project I maintained for a while, a while ago—it still has at least one file of pre-ANSI C (with the K&R style function definitions) alongside a bunch of C and C++ that compiles under C++14.

The story is that this actually runs a service that I needed to migrate from an old CentOS server to a new Ubuntu server. Despite it being a 30+ year old project, and my not having touched my fork in ~5-6 years, it all just compiled and ran (specifically configure && make resulted in a working binary on the new server). I can't think of any other piece of software I use that I have that kind of confidence in just working!
