Well, false alarm.  Maybe not _completely_ solved.

I made sure that all implementations emitted objects, e.g.  by moving
null constructors to the source and including asm("") in the body.
And this helped!  So I conclude that (perhaps appropriately) the gcc
inline-small-functions is removing null-body functions.  But: (1) it
is difficult to track all of these down in a large code: and (2) I
believe that this does not cover all the cases of that optimization.

So in the end, I'm stuck with "-O3 -fno-inline-small-functions" which
does seem to give me working code and no obvious performance hit.

Any thoughts??
