Thank you!

Using this approach for up to MUL_512() feels risky, though.  That's a
stress test for the assembler.  Perhaps there's another way that would
not involve multiplying by a number this large.

I'll try to find time to look into this a bit later, although I have
other (non-JtR) things to focus on first...

Thanks again,

Alexander
