As far as I know, on GNUstep at present there's no portable way for 
applications/libraries to include runtime.h specifically, due to the two 
possible directory prefixes. If you include Foundation/Foundation.h, you'll get 
the right runtime.h included as a side effect, though. (But not on OSX)

On OSX, you use #include <objc/runtime.h>.

GNUstep make doesn't support that now though, does it? If you wrote 
appliactions / libraries that used #include <runtime.h>, it would also require 
tweaking to get them to build on OS X.

I wonder if it would be possible to have the ObjectiveC2 compatibility 
runtime.h be installed in such a way that #include <objc/runtime.h> picks it up?
