THANK YOU.

Gold star for Pierre.

This is exactly the kind of data I was looking for.  It seems to me that
this suggests that there really is no issue that we have to worry about
in this case.

Out of curiousity, does building the executable 1) without debugging options,
and 2) with the -s option, also result in non-sparse files?

I'll test this myself when I get back to a windows computer but that won't
be for some time.

I really appreciate your checking into this, Pierre.
