[boost] Big integers - current status? any progress?

From: Paul A. Bristow (boost_at_[hidden])
Date: 2002-10-08 11:40:07

Helmut Zeisel submitted an unlimited integer library 3 July 2001,
big_int_20010821.zip

and more recently Roland Garcia submitted bigint.zip, which works to compute
factorial
using MCVS 7.0 with trivial changes.

big integers are an important library item.  Is there any plans and/or update on
these?
Is a Formal review envisaged?

PS (I have failed to get Helmut Zeisel's to compile using MSVC 7.0, perhaps due
to some macro id failure? Suggestions?
