Well, the script I have now simply skips the first fews lines (which contain the timestamp) and then compares the rest of the two files as two long strings. So the C equivalent would be fairly short as well. And nothing at all like cmp and diff. It simply tells the user whether the files have different lengths or whether the contents are different.

I will do that - the drawback would be that the user needs to have MinGW installed in some form. Also it may not be all that evident where the MinGW tools are installed. Still, worth a try.
