Patch to fix int64t / long long conflict in sscanf.

Build on Fedora 16 64 bit host fails. Conflict in sscanf between SCNx64 (llx)
and SCNd64 (int64_t). Compiler defines int64_t as long.

Patch for basictypes.h below resolves build problem. Passes unittests. Since
'long long' was hardcoded in int_types.h, I also hardcoded it in basictypes.h.
Since long long should always translate to int64t (when available), seems to
make sense.
