[Box Backup] problems with large files?

Hi Paul,

I'm confused. Looking at my development system, which has cygwin's mingw 
installed (3.4.4 cygming special), I have two conflicting definitions of 
struct stat:

 	/usr/include/sys/stat.h:
 		off_t st_size;

 	/usr/include/mingw/sys/stat.h:
 		_off_t st_size;

I was obviously assuming that the latter was correct when I wrote this 
code. Now I'm not sure at all. However, I'm not convinced that it makes 
any difference. Every definition of off_t and _off_t that I can see uses 
signed long.

Cheers, Chris.
