Good question, I don't know. All I know is what I get in the warning.

I thank you for your reply, however it doesn't really answer my
question. First, I'm only using gcc, so Borland and MS C don't count.
Second, I'm obviouslly using gcc's -Wtraditional setting for these
errors to come up, so my question was: how do I get rid of these errors
so that everything works correctly while still using -Wtraditional?
Should I even be using -Wtraditional?
