--- Comment #5 from David Brown <david at westcontrol dot com> ---
I agree that warnings to match something like the MISRA coding standards would
be best done as a plugin.

But I believe that in this case, warning on octal literals would be quite a
small addition to the main gcc code.  I am not familiar enough with the gcc
source code to implement it myself (like many people, I blame lack of time) - I
therefore registered this enhancement request in the hope that someone was /is/
familiar with this part of gcc would be able to make the change quickly and
easily.
