this could have worked those days as the compiler might was written by
the same people as the program.

Any way, I ran recently in a K&R source which compiled and worked as
expected on FreeBSD 10 and 12. The warnings have been nearly endless.
As the source was just a few hundred lines, I do not know how relevant
this is.

Good luck!
