A pity you dont.  All that the above means is that ANSI C doesn't force
you to optimise code.  As plenty of people have pointed out, it doesn't
force you *not* to optimise code either, nor does it limit the extent
of your optimisations.  You just optimise *after* the C-to-intermediate-
code translation is done.
