BUILD: WARNING: The command line option -s has been deprecated. Please use -c instead.

I'm getting this warning when building in Eclipse.

My SDK manager ABOUT shows V1.0.3

The SDK I'm using is 4.0.9, the latest non-beta that is listed.

In Eclipse, when I select Help | Check for Updates, the update available for Connect IQ IDE and SDK Manager is 4.1.0 beta. I'm not thrilled about loading a beta.

Can anyone tell me what has to happen to address this warning, or whether it's safe to ignore it (seems unlikely for the long term).

Thanks
