Is there a reason not to trust the latter? 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". Stefan
