​I think it's a mismatch between what the cross compiler has and what the
host compiler has. I've never figured this out.

So, I think it's best to start with a lisp without double-double support.​

​Support for double-double was apparently done by 19e, so your best bet is
to do a checkout from 19d.  I think everything that you've done up to now
still applies.

Once that is done, we can consider adding double-double for alpha. It's
relatively easy, but you'll have to write a bunch of vops. They can
probably be copied almost verbatim from the sparc or ppc ports with small
changes in the actual instructions.

​One last thing:  remove :alien-callback too. Alpha doesn't support that.
​

​Hopefully this will get us farther along....
