Sporadic differences after a bootstrap

Sporadic differences after a bootstrap

[Eli Zaretskii]

After bootstrapping with today's CVS, two files become different from
what's in CVS:

Why does this happen?  Is this a real problem?

Glenn is using `generated-autoload-file' in some files so their
autoloads are in their "parent" file, instead of loaddefs.el (for
example, ibuf-ext.el's autoloads now go into ibuffer.el, dired-*.el's
into dired.el, etc.). The downside is that these parent files must be
updated into the CVS whenever the checksum varies.

If it bothers people, the other way to do this is to have a completely
generated file (eg rmail-loaddefs.el) that is not stored in the
repository at all. Either way is fine by me.

That seems a bit cleaner to me, but it is not really that important.

I should also have said that ps-print has been using this mechanism
for some time, and it doesn't seem to have caused too much trouble. So
now that this has settled down, if people give it a chance, I don't
think it will be noticeable.

Both ways are currently used in Emacs (many of them setup by yours
truly), and the deciding factor was generally the size of the file.
If the rmail-loaddefs.el would be tiny, it's not worth the trouble.

Just commit them when it happens.  The last one modifying the referenced
files didn't bother to update the autoloads.
