Remember that most of the gets() debate was over NetBSD's non-ANSI
behavior of printing a warning message the first time it was invoked.
This has been changed so that a link-time warning is issued instead.
I would agree with the software author about puting an OS specific code
in an application. Perhaps he doesn't realize that he's using gets()
instead of fgets()?
Since the buffer he uses is only two characters, you could probably find
a legitimate bug report that would convince him to change to fgets().
What happens when you answer the prompt with:
Yes. Please. I really, really want you to do it.
That would probably overwrite something important :-).
