I tried to compile and run some C code from 1991 using a modern C compiler: https://github.com/sshine/dikumud/commits/master/ https://github.com/sshine/dikumud/commits/master/ It wasn't plug-and-play. My guess is that when Rust code gets 30 years old, the problem would more likely be that you can't find an already compiled compiler that will work for that old code, and that the compilers themselves need bootstrapping. So you'll just fast-forward the code to work on a new compiler instead.
