Sure, I can see that, but I am wondering why the hand-written autoloads
were just not replaced with generated autoloads in loaddefs.el? That is
the simplest solution. Simple is good (so long as it's not simplistic).

Or, as an alternative, implied by this post:

Which was your comment at the time. In this scenario, the reftex-* files
would generate autoloads to reftex-loaddefs.el which reftex.el would
require. This preserves the current behaviour, but avoids files which
are both source and generated.

One response to this was:

But configure isn't under versioning any more. And Stefan's MD5 patch
was the other. It's certainly true that Stefan's solution massively
reduces the problem, but it doesn't fix it, since a *build* can still
produce changes in versioned files.
