Well, I hadn't thought it through, because lines may have a variable
height. Duh.

And I can increase the buffer font-size many times over without
changing the result of frame-height (or -width), so now I don't
understand what "number of lines available for display" in the doc of
frame-height means.

I guess it means number of lines in units of the default face? So I
guess that's what my original question meant.

I'm not going to be able to document the Windows behaviour in any
case; maybe you'd like to do that?
