It depends on the Compiler. Not all C-compiler implementations support 64 bit
integer types. Microsoft C for instance does. Furthermore the corresponding
types - if supported at all - are not standardized. Some compilers call them
"__int64" and others "long long". If an author has code which is used for
various platforms with differing compilers, then it's a bit of a mess.
