-Wall -pendatic options warn about a lot of issues that are often programming errors. I would like to sugest reversing the warning policy so that warnings should be explicitly turned off instead of on. The rational behind this is that, the programmer should be warned about possible issues with his code. In case the programmer knows what he is doing he can still disable the undesired warning (but he has to do so explicitly).
As a bug this will be very likely ignore (I'm even tempted to close it as WONTFIX or WORKSFORME). Please raise policy issues on the appropriate mailinglist (gcc@gcc.gnu.org).
Please close. Will report to mailing list. Thx for the comment.
Closing as requested
