Re: 64-bit instruction mask emitting as signed hex value

Interesting.  I'm running Guile 1.8.7 on Mac OS X Lion (10.7) and installed it with MacPorts, the Portfile for guile 1.8.7 at revision 2.  I think the next step is to download the source directly from gnu and see if it was simply a compile option that was missed.

And issuing the identical statement on my installation is

guile> (number->string 18446744073709551615 16)
"-1"

Thanks for the additional clue.
