OK, thanks.

That's useful to know. thank you.

So I should ignore the entries in the docs about sparc64 then. I'll
try that.  At the moment I have a downloaded binary version that
works. but I can't get a binary of binutils-2.15 so I'll probably
not get much chance to try this out for a while.  Anyone hoping (!)
for further reports from me about this shouldn't hold their
breath.:-)

Thank you all for your helpful and patient input.
