Try this with -Os instead of -O3 and see what happens.

Steve, I think you know a little more about C++ compilers than I do;
any idea why g++ is ignoring the inline keyword to the detriment of
this program's performance?

Obviously, hand-optimisation is a time-honoured art, but on something
as basic as this, you'd think the compiler would get things right.
