Luc's right. The first reference to defvaralias is:
2001-10-04 Gerd Moellmann <[EMAIL PROTECTED]>
This adds `defvaralias' and `indirect-variable'. Changes not
directly related to this feature are there to gain the same
performance again as before variable aliases.
and the previous entry on ChangeLog.9 is:
2001-10-04 Gerd Moellmann <[EMAIL PROTECTED]>
* Branch for 21.1.
so it seems like Gerd branched for 21.1 and immediately afterwards
commited a bunch of things on the main trunk, `defvaralias' among
them.
It's a little weird, though. `defvaralias' is mentioned on
lisp\ChangeLog on 21.[1-4]:
2001-05-20 Gerd Moellmann <[EMAIL PROTECTED]>
* font-lock.el (lisp-font-lock-keywords-1): Add `defvaralias'.
and the corresponding font-lock code indeed has:
"(\\(def\\("
;; Function declarations.
"\\(advice\\|varalias\\|alias\\|generic\\|macro\\*?\\|method\\|"
[etc]
even when the function is not available.
And, from 21.2+, lisp\w32-fns.el has this:
;; Set system coding system initially from locale-coding-system.
;; In future, when defvaralias is available, this will become an alias.
(set-w32-system-coding-system locale-coding-system)
