c++.command-line - Unused variable warning

Is there a switch to report "unused variables" as warnings?

I currently use VC6 for software development, and appreciate the warning that
I've declared a variable which is not referenced.

I'm a new user of DM, and I can't find a similar warning setting. Advice from
more advanced users is appreciated.

There isn't one in DMC, for the rather personal reason that I like to #ifdef
out code for various reasons and not need to comment out the declarations
for it, too.

Hahahahahah ... what a pleasant change to hear direct from a product developer
:)

If you should be in a benevolent mood one day, and think about including this
feature, make it default to OFF and you won't have to change your working
habits.

Thanks for the response.

Ron.

As Walter already pointed out, there is none, so if you would like to
have this warning and perhaps for other possible bugs in your code, I 
recommend you look at Splint http://www.splint.org/

Thank you, Cesar.

I tried splink, and almost had a heart attack at the number of errors and
warnings reported on what I thought was good quality code.

Once I found the -weak command line parameter the smile started to return to my
face. I'd like to move towards stronger checking, but I don't want to rush into
littering the code with the on/off comment flags apparently needed by splink at
its most defensive.

Ron.
