"Underfull \hbox" means that there's too few characters to typeset a
line of text without making it ugly.  TeX tries to fill lines, but
when the Texinfo sources requests a fixed-width typeface, such as with
names of variables and functions, it cannot do that.

The solution is to rearrange text around the problematic part.  I
agree with Glenn that doing this now is a waste of effort.

Bottom line: ignore those errors.  ("Overfull boxes", OTOH, are more
serious.)

As the Texinfo sources change, these issues can appear and disappear.
It's normal.  Likewise, they can appear with one paper size and not
the other.
