I disagree. Choosing the compiler options is exactly the job of the
installer, packager, or distributor. That's why you can specify CFLAGS on
the command line after all, and most distributors' build environments make
use of that.

I don't think we're doing anyone a service if we spread wild speculations
about how risky certain compiler options are. If your compiler creates
broken code, don't use it. Packagers are expected to know about their
compiler. If they create broken packages and behave irresponsibly about
it they won't be making packages much longer.
