It looks like you've just solved the problem.

Neither macros nor inlining of functions is necessary for GNU systems -
just compile with -O3 (or -finline-functions) and you'll get better
optimization than we can provide manually.

This doesn't address people on other systems, but I would hope that
either they can compile with gcc also or that their compiler will
provide comparable optimization.

If you still want to compare inlining to macros, I imagine with -O2 or
less gcc will inline those functions marked as "inline" and not any
others.
