Yes, but, as you know, that is in hashtab.c, not hashtab.h.  I don't
see any reason they need to be in hashtab.h at all.

If we want them in hashtab.h, then I think they should be macros.  But
upon further reflection, I'm pretty sure we don't want them in
hashtab.h at all, and I think we should just remove "inline" in
hashtab.c.
