Wayne,

In 'C' long long's are 64-bit on 32-bit architectures; however,
and unfortunately, long long is only part of the 'C' standard
and not part of the 'C++' standard.

i.e. in stdint.h you find

 typedef long long int64_t;
 typedef unsinged long long u_int64_4;

but stdint.h is a 'C' header file and not a C++ header file.
