As far as I can tell, that exactly what's happening here:

> #define environ (*_NSGetEnviron())

It appears to be substituting in a call to some Cocoa function. This seems to be The Workaround, at least according to Google. From the name, it seems to be the a description of the environment, so I can't see why this wouldn't work.

What file does it go in, though! I promise I'll come back and tell you if it doesn't work. ;-)
