Hi, I compiled the Wavpack lossless codec tool and found a problem in function DoGetFileSize() that on unix systems use this code:

struct stat statbuf;

    if (!hFile || fstat (fileno (hFile), &statbuf) || !(statbuf.st_mode & S_IFREG))
        return 0;

    return (int64_t) statbuf.st_size;

The problem is that it returns zero. So I used lfilelength(fileno(hFile) function that works. Does it mean that there's a bug in fstat or it is not implemented at all (just a dummy)? Does lfilelength() supports >2GB files on enabled filesystems (like NTFS under NTVDM)?
