I'm not sure if we already have a canonical way of referring to this,
but IIRC we already use "K&R" in other places, which may be more
meaningful than "function with no prototype".
I disagree. I think very few people know what K&R syntax is, outside of
a vague memory that they should (but usually don't) remember to write
"(void)" instead of "()" when declaring a nullary function. ANSI C
programmers should at least be more familiar with the concept of a
prototype. The vast majority of people encountering this error are
going to be people who've accidentally written their nullary function
without void.
...not that there's really any point to declaring a nullary function
fastcall, at least not in any of the conventions calling themselves
'fastcall' that I know about.
That said, maybe we should say "K&R" and just provide a fixit to put
'void' in the argument list.
John.
