Use _stat64() to support file size >2G

Browse Source 
1. Newer VC runtime stat(), when using 32-bit file size, returns error
   if file size is >2G. For file existence check, using 64-bit file
   size is more accurate as files bigger than 2G would be reported as
   non-existing otherwise.
2. <sys/stat.h> is required for VS2013 or before.
