	MS docs tell us the __int64 type has no ANSI equivalent
	I've checked and currently a 32bit long leads to problems.
	The code could probably be altered to get around this 64bit
	precision requirement. If not a custom class could be found
	(or implemented fairly easily). However, as GCC supports
	"long long int" I'm giving this low priority until someone
	complains...
	
	"ISO C99 supports data types for integers that are at least 64 bits wide,
	and as an extension GCC supports them in C89 mode and in C++."
	
	I've heard some compilers have a "quad int". If "long long int" does not
	work, try that.
