                         printf("%10lu ",sx.st_size);

The st_size field in struct _stati64 isn't an int, but a 64-bit
integer (long long in gcc parlance). The "l" printf format modifier
means "long", and a long is 32 bit just like an int. To print long
longs with the Microsoft C library (MSVCRT), use the "I64"
modifier. (Yes, this is not what the C libraries on Unix typically use
(they tend to double the "l" modifier), but then nobody says MSVCRT
tries to emulate Unix.) I.e.,

                         printf("%10I64u ",sx.st_size);

Also, remember, gcc -Wall is your friend.
