It helps there are automated tools for converting old style K&R function declarations to the new ANSI/ISO style, like protoize. But K&R C is now so dated, protoize was removed from GCC 4.5 and onwards. When (in a bout of idiosyncrasy) I wanted to convert some ancient K&R C to new style a couple of years back, I ended up putting GCC 4.4 in a Docker container to make it easier: https://github.com/skissane/protoize https://github.com/skissane/protoize
