GNU CC as it currently runs on my box emits conditional instructions.
Produced code is 20% larger and 20% slower than /bin/cc produced code
(numbers may vary -20%+80%).  (These numbers will get better when I
start hacking again.)  Also, GNU CC takes quite a lot more time and
memory and /bin/cc.  I don't expect it ever to run comfortably on a
2Meg RISCOS machine.
