That's correct and that's what an ANSI C compiler for the Mac should do.
In C, you should *always* use \n as a line separator in strings.

I get the very same error when I run your example code on a Sun,
which uses \n as end-of-line.
So, the error is correct and expected.

Like I said, you should *always* use \n as a line separator in strings,
as if you were going to write them out.
