defvaralias isn't defined in emacs 21

[Göran Uddeborg]

Trying to use the combination emacs 21 and vm trunk fails on startup with the error message that "devfaralias" isn't defined. According to the NEWS files, it was introduced in 22.1.

Fixed in revision 1022.

The fix doesn't quite work. The defvaralias function is used before it is defined. Below is a stack trace from starting emacs (with --debug-init)

Debugger entered--Lisp error: (void-function defvaralias)

Added another fix in revision 1035. The macro was getting loaded a bit late in the game.

Right! Using revision 1035 seems to work.
