I don't know about Apple Mail but it's generally possible to compile OSX
applications under GNUstep since Cocoa and GNUstep are the same API
in large parts. However, Apple has made some additions to Cocoa that didn't
make it into GNUstep (at least not know). The URLLoading framework comes
to my mind.

Exactly. Everything that is not in the Foundation/AppKit API will cause
problems. CoreFoundation is also not available.

In general, I would say that it's not too difficult to have an Application
working on both OSX and GNUstep (GNUMail and Vindaloo are examples).
I usually make my stuff working on both platforms.

This would be really cool. I'm using TextMate on OSX for quite a while now
and it's really a master piece of work.
