Going off at a tangent....what would people think of the idea of
switching to -Os in $RPM_OPT_FLAGS _after_ FC5 is released?

If it results in some form of improvement in performance, I'm all for it.


The "s" in -Os stands for "size", not for "speed". So if -Os compiled
code-execution is faster than the default CFLAGS, something must be
broken elsewhere.

Not necessarily.  The reduced size of the executable makes more
efficient use of CPU cache, which can have a net result of increased
speed as well.
