I suspect that there's a problem with the size of the literals on the 64-bit compilers. Does one declare a 64-bit literal by appending a double L ('LL')? If so, then I'll give that a try.
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 );
Thanks for that information. I think what I'll want to do, for a first cut, is always produce 64-bit literals for 64-bit capable compilers. I'm going to wait until after the review period to start on fixing the 64-bit support. Since I don't have a local 64-bit compiler I'll be working blind and my first few efforts will be dead wrong. At an initial glance it looks like 64-bit support should be achievable without heroic efforts. But it certainly won't come along for free. Thanks again Reece. Scott Schurr
