> A question about the timestamps in loaddefs files:
> Why do we need to store the last modtime for each input file?

Not sure, to tell you the truth.  Given the time it takes to generate
the loaddefs.el file, there's definitely a chance/risk that the file
gets modified between the time it's read by autoloads.el and the time
the corresponding loaddefs.el is written.

Not sure how serious this risk is, tho.  Worth a try.
What I suggested for the "reproducible build" was to do something
simpler (in terms of safety of the change): just strip the comments from
loaddefs.el during "make install".
