PR# 2398 Files larger than 2 gigabytes

Synopsis: Files larger than 2 gigabytes

Description
The feature 'count' in FILE returns a 32 bit integer.  Obviously this isn't going to work for files with a length of more than 2 GB.  In my case I was checking to see if the file was less than 1MB.  It was.  In fact, the size was negative!  In WIN32 you can retrieve a file's true size using stati64.

struct _stati64 stat_buf;
__int64 sss = _stati64("file.ext", &stat_buf);
__int64 size = stat_buf.st_size;

However, we are going to need a INTEGER64 class, even a rudimentary one.  I will work around the problem one way or another.

Dear Randy,

Next release of ISE Eiffel you will get will support INTEGER_64, so
this problem won't occur anymore. However, the support is not yet
complete and the part handling with files have not been updated.
