Something as simple as adding an MD5 digest plus a mime-type of a source 
file as a "finger-print" in a separate section would have worked.

It wouldn't even need to change how object files work but would preserve 
1:1 mapping of sources to obj. And we could have gone this way in D but 
since C objects produced by other compiler won't have this ability it 
would be quite limited (and conservative).

Yup, UNIX is so UNIX.
