Generally, the C compiler generates code that's quite distinctive (at least
PCC does, not sure about Dennis' compiler). People writing free assembler
tend to do really weird things for function entry / return.

And it will likely tell you if it's some weird wrapper around another
binary, though that wasn't too common at bell labs.
