Thanks for this explanation. (I have used Apple hardware for some
years, but always running GNU/Linux.)

I would like your opinion on the following, if you can share it: in
the end, I solved my problem not by using the updated gnulib, but by
assuming a conformant C99 compiler, and directly using the "inline"
keyword. This would not work on clang as shipped with old Mac OS; is
it reasonable in your view for me to expect users on such systems to
have installed a newer compiler? I see that MacPorts does ship
up-to-date GCC.
