Yes, I understand and share your concerns here. Actually, implementing
this binary compatibility could be more harmful to the project (by
diverting people from recompiling) than beneficial. Hmmm..., that's
an interesting perspective.

Anyway, I didn't consider the issue from this perspective as I asked
about that glibc trick (didn't get a reply yet); just being interested
in the technical way to do it. I'll have to read more about ELF and
exec() to figure it out.

Thanks for the feedback.
