[h-e-w] Emacs 21.3 for Windows on AMD64 and Itanium

[Dallman, John]

I asked a few weeks ago about versions of Emacs for Windows 
that might run on Itanium and/or AMD64 Windows, because the 
elderly version we're using here doesn't work. 

I just got a chance to try building 21.3 from the source kit.
I did this for plain x86, (rather than try to port all of Emacs
to the weird LLP64 data model that Win64 uses) and that starts
up and runs on both AMD64 and Itanium. The custom major mode we 
use here doesn't work yet, but it's a step forwards. When we
have that working, we can think about moving all the ordinary 
Windows users up to 21.3.
