The overflow case has:  "correct value"
While the underflow case has: "result"
-> This was the original text and I didn't want to change things not
related to this paper's purpose. I think if we want to change this, we can
ask for it editorially (as a separate paper or request).

Would it help any to add to 7.22.1:
For freestanding implementations, neither errno or the FP exception flags
need be affected by any of the functions in this clause.  Also, locales
need
not have any affect on these functions.
-> I like this idea. I will add it to alternative 1, exclusive as it seems
like a removal.

The FP numeric conversion functions in <stdlib.h> are:
atof(), strfrom*(), strtodN(), besides strod/f/l().
So, maybe adding "some" so the last paragraph has:
"... may also use some features ..."
- Since the last paragraph is part of the errno -> errno + exception
change, I don't think this fits there in isolation. It is a good point
though that needs the specific group of functions in alternative 1,
inclusive as well as the last paragraph you suggested.

At very end: "when is"
-> I don't see this. Did the renderer take out the <stdlib.h> in the last
line? Mine does not, but maybe another one does, somehow assuming it is an
HTML tag?
