configure re-run each time version.el changes

configure re-run each time version.el changes

[Eli Zaretskii]

Why is config.status dependent on lisp/version.el?  This causes Make
to re-run the configure script each time version.el is modified, which
seems like an unnecessary annoyance.

Andreas Schwab added that dependency in 2007 to fix a problem back when 
Emacs was managed under CVS and did not assume GNU Make.  Please see 
this thread:

I haven't looked at it carefully, but I wouldn't be surprised if the 
dependency (or something like it) is still needed.  I'll CC: Andreas to 
give him a heads-up.

Thanks.

AFAIR, at the time, we updated the Emacs version by grepping
version.el, and perhaps that was the reason for the dependency.  But
nowadays we do that in configure.ac, so I wonder if the version.el
dependency is still needed.

This has nothing to do with CVS or GNU Make.  It came obsolete when
ceased to be the authority for emacs-version.  I've removed it.
