I think we can say that K&R function declarations are truly obsolete.  In
~20 years of hacking C, I've only seen very old code which uses them.

Presumably these declarations are still widely used in compiler validation
suites but nowhere else.

Approximately when did they become obsolete, i.e. not used at all for new
code?

[Context: I'm writing documentation for Emacs's C Mode.]
