I'm not too familiar with ELF either.  I know a little about which
C variables live in which section, e.g., .rodata is storage for string
literals.

Yes.

I was thinking of something like the HTML <acronym> tag.  In my browser,
<acronym title="tooltip">foo</acronym> renders «foo» with a dotted underline
whose raison d'être is your concern (a).  I assume the user agents of
people in categories (b) and (c) have similar solutions.

In any case, displaying the values in a comment is probably better since
it makes the information available without a user action.  (As I said in
my last email, the comment should be exempted from being diffed.)
