I would *love* to have a bignum library in Boost. Although I like
GMP, its difficulty of building on VS, and its highly restrictive
license (for my projects anyway, completely free and I give out source
when asked, the GPL will not work with the bulk of the code and the
purposes of the projects I work on, for an open-source license, the
GPL is absolutely worthless, I prefer a BSD or Boost style license)
makes it rather absolutely worthless, even considering all the work
that has gone into it, seems so wasted. It should be such a generic
thing (a bignum library), yet they completely destroyed the usefulness
of it. So yes, I would love one in Boost, just one other library I
would not have to manage separately and would have a lot of work done
on it as well. I think work mainly done for the x86 (-64) and the
other top 3 or 4 platforms (ppc, arm, etc...) would be more then
enough to make it very useful, with slower pure C++ fallbacks for
