I assume you have already looked at the horrendity of the code
presently generated by -O0. It's pretty unusable as it is. Who would
really want to use gcc under the influence of "worse than -O0"?

Off the top of my head, if you insist on this approach, at least
guarantee that generated code is no worse to debug. That is the only
reason *I* use -O0, to debug.
