That may have been true years ago, when the tarballs themselves were
the main way that one could find out how to do maintenance.  But that
long ago stopped being true for Emacs.  If I wanted to come up to
speed on how to build Emacs for MS-DOS, the first thing I'd do would
be a Google search, which would point me at places like
<http://www.emacswiki.org/emacs-fr/EmacsForDOS> and
If these places contain extraction instructions, that's good enough.

Even if -n is currently error-prone in GDB, that does not mean
that the approach is inherently error-prone, or that it must be
error-prone in Emacs.  For example, it should be pretty easy to check
emacs-25.chg automatically; is that done with GDB?  If not, and if
checking is done by hand, I can understand why it might be error-prone;
but an automated check should substantially reduce the number
of errors.

I hope that you don't include me in members whose knees are jerking.
Personally I would just rename the files in gnulib and be done with
it, as none of the name changes seem to be onerous.  However, we don't
seem to have consensus for that now; I seem to be the only gnulib
developer who would go that route.  Also, the problem of non-8+3 file
names does not seem to be limited to gnulib-derived files.

All in all it sounds like automating the renaming on the MS-DOS side
would be a reasonable thing to do.  This is a bit of work but doesn't
seem that hard.  And if we get the automation working well with Emacs
we could then apply similar ideas to GDB as well, and make GDB
development less error-prone on MS-DOS.
