This just bit me *HARD* on a fairly large project, I couldn't figure
out what was wrong and was pulling my hair out for a bit... but I
finally tracked it back to this:

If an included file uses an #ifdef wrapper to prevent multiple
inclusions, absence of a newline after the #endif at the end of file
causes it to report an unmatched ifdef.

Here is a test.csd and include.csd

As it is it will fail.  Adding a newline to the include file will fix
it.  This doesn't strike me as the intended behavior, but just figured
I'd ask before filing a bug.
