I got the same results that you did.  I was planning on
investigating this morning, but it looks like you beat me to it.
I ALSO built 6.3 with a non-standard port, so that I could keep
my current database live while I work on this.

I'll try your suggestion, but I'll also try rebuilding using the
standard port, to see if it makes any difference.

Re: your suggestion to use __alpha and not worry about the
makefile, I'm a little uncomfortable with that.  DEC's cc will
actually output different symbols, depending on the use of the
- -std flag.  I'd rather have something that we have explicit
control over, rather than relying on the compiler like this.  I'm
not violently opposed to useing __alpha or anything, it's just a
preference against it.
