[boost] Small problems with sandbox/bigint_gmp

Hi,

I find the C++ version of GMP to be a bit bloated. So I searched another
'big integer' library. I gave a try to the bigint library in the
sandbox. I used the GMP version of the library since its implementation
was rather trivial.

However I needed to apply this patch for it to work:

--- bigint_gmp.hpp.old  2003-10-28 17:06:07.000000000 +0100
+++ bigint_gmp.hpp.new  2003-10-28 17:07:15.000000000 +0100

 };
  
-
+inline
 void swap(bigint& lhs, bigint& rhs) {
   lhs.swap(rhs);
 }

I also needed to add a 'data' member in order to get a reference on the
underlying GMP datatype. The GMP library is indeed a lot more powerful
than the small subset present in the bigint library. May I suggest its
addition?

Guillaume
