Oooh, good point, I had forgotten about that little detail. Yeah,
we'll lose that optimization if we move the code out-of-line.

So I guess a fallback position is #if __gcc__ use a "static inline"
function, else the existing code. That would at least let us get
rid of the global-variable assignment in gcc-based builds.
