Scrolling down to line 1979 (or so) :

#endif  /* CIRCLE_UNIX */

and further down (line 2053):

With #if's you can nest them like you can normal if's.  The effect here
is that some signals are on both macs and unix, and some only unix.  The
standard way to show which endif closes which #if is to add a comment.
Similair to what you might do with a closing } in long bits of nested

Without out an #endif I'd expect you're compiler to complain in some
