GMP.

LGPL. Standard download from official website is designed for GCC. VC++ port is available from here.

I can't in all honesty recommend GMP for serious work since it has the nasty habit of exiting violently on out-of-memory problems. This is, in my opinion, unforgivable in what's supposed to be a general purpose library. Don't get me wrong, it's still good and blindingly fast, but only for personal or non-production stuff where you can put up with crashes. – paxdiablo Feb 03 '11 at 17:58

I have not used it, so I'm pointing you here blind:

LibTomMath by Tom St Denis: http://libtom.org/

Public Domain license. Website mentions that the library builds out of the box with GCC 2.95 [and up] as well as Visual C++ v6.00 [with SP5] without configuration.

A companion book is available: http://www.amazon.com/dp/1597491128
