Clang status update

[David Chisnall]

Hi Everyone,

I've fixed a few clang bugs this week, and it's now capable of  
compiling the entire Étoilé tree with both the GCC-compatible and non- 
fragile ABIs.  If anyone wants to play with it, grab the latest svn.

You need libobjc2 from GNUstep svn to use the new ABI and you need to  
add -fobjc-nonfragile-abi to your OBJCFLAGS.  This lets you hide  
instance variables away from public headers.  This is needed for the  
fast forwarding (-forwardingProxyForSelector:) and non-fragile ivars  
to work.

With both ABIs you get fast enumeration and declared properties.  Both  
of these require either libobjc2 or the ObjectiveC2 framework from  
Étoilé.

You do NOT need to compile GNUstep with clang, and you can mix the two  
ABIs in the same program, although if you subclass a non-fragile ABI  
class with a fragile ABI class then things will break.
