I need to manipulate big ints under windows with gcc : big means for me
64 to 256 ( mostly 128 I think ), but the code has to work fine on 32b
architectures such as a pentium3.

- - how to declare such variables ?
- - how to declare constants ?
- - shall I use libraries ? which ones ? ( I can only accept non licensed
libraries, since my code is close source : no GPL accpeted )

- - which operations will be supported on those numbers ? - I mostly need
basic crypto functions, such as additions, XOR, multiplication, and
bitwise manipulation .

Thank.
