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.

/opt/SUNWspro/bin/lint -V says:

  lint: Sun C 5.5 2003/03/12

I'm not passing any options.

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.
