Anyone working on linux Alpha?

I'm talking with the Debian porters for Alpha architecture, who are having
trouble getting 6.5beta2 to work properly.

Is there anyone using this setup?  If so, do you get a good regression test
result? (They don't.)


This patch was necessary for them to get 6.5beta2 to build at all:

This is required because of problems with egcs:
