for the current YYUSE definition, I do see this warning:

As I understood it, this will happen with ancient lint implementations
that don't support CONSTCOND comments; it shouldn't happen with newer
lints (unless you ask them to ignore CONSTCOND comments). But it
appears my understanding was wrong.
Your understanding was probably right. I'm not in the habit of using lint,
and I'm not personally concerned about its warnings. I was trying to come
up with a YYUSE() definition that would allow me to pass structs as
parse-params without creating any additional lint issues for other users.
Sorry, I didn't realize my lint installation was too old to be relevant.
Which implementation of lint are you using, and what options are you
giving it?
/opt/SUNWspro/bin/lint -V says:
lint: Sun C 5.5 2003/03/12
I'm not passing any options.
How would you tell your 'lint' version to not output that
warning? I'd like something that works at the source code level.
No clue, and the man page didn't help. Maybe my lint is too old.
In any case, I guess this means the new YYUSE() definition I posted might
need testing with newer lints.
