By checking if foo.obj is outdated in regards to foo.d
The compiler doesn't know that foo.d was built into foo.obj, it has no
way of knowing that.
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).
