Version 2 implements above suggestions (and successfully builds).

Thanks for your response, bad form of me to have done this. With your
direction I was able to build the docs. I was not able to get the test
suite running though. Since I am not across the source I am unsure if
the documents I have written for .8byte are correct. I am a bit out of
my league documenting things I don't understand but if you have the
time (and patience) to please point me in the right direction I will
try to verify it before submitting version 2. So far I am under the
impression .8byte and .quad are alias'. Surely .8byte cannot accept 16
bytes however, like .quad can if bignum-16 is set.

thanks,
Tobin.
