Seriously, there is a clear direction on how you can go about improving
things. Start putting some pressure on the FSF guys to actually give
us sane warnings in gcc.
That's what it all amounts to: -Werror is unusable for production because
of the false positives and the HUGE variations from one release to the next.
If there was a way to have something like -Wsafe-deadly-errors-only
then I'm pretty sure *everyone* would be happy to use that.
But no, 20 years down the line, gcc is still some experimental compilers
that gains useless warnings one release, false positives the next, and back
down from all that to invent more arcane stuff.
