This will depend on the compiler. I am not sure what GCC does, but for MS 
(and compatible compilers - Borland, CodeWarrior, Intel and others) you do:

   __int64 biglit = 2i64;
   unsigned __int64 biglit2 = 2ui64;

If GCC has the ll and ull prefixes, you could create a macro for defining 
signed/unsigned 64-bit literals either where uint64_t is defined or in 
Boost.Config. e.g.:

   uint64_t biglit = MAKE_UINT64_T( 2 );
