This is the right thing to do: you should take config.h from the Alpha
and plug it into your Linux build. You want the compiler to generate
.hc code for a 64-bit system, and using the Alpha's config.h will cause
it to do this.
However, you might be unable to compile the resulting .hc's down to .o
on the Linux box, which means the build might fail. This is harmless,
because we don't need the .o's, but you might need to work around it
somehow.

Check out the latest code from CVS on the 6.0 branch. I've just merged
across an important fix for unregisterised code, too.

package.conf and .depend* shouldn't be necessary, but I haven't got as
far as checking the HC bootstrapping phase here yet.

I'll take a look at this.

Committed, thanks.

I don't know anything about this either.

This shouldn't happen; I'll look into it.
