I'm not sure K&R1 said that, but if so, they were wrong, since AT&T's
own PCC rejects that with two "syntax error" diagnostics.
>You *cannot* define this function as:
> int ( * frfp (p0,p1) ) () int p0, p1; {}
And PCC accepts this one.

It's sure not a quiet change in UNIX practice.
I don't know of any compilers that required the former construct
instead of the latter.
