libobjc2 ready for (gentle) testing

[David Chisnall]

Hi Everyone,

For the last few days I've been using the runtime from libobjc2 in  
GNUstep svn as my default runtime.  On my machine (FreeBSD 8) it  
builds cleanly with both gcc and clang and works with a mixture of  
code compiled with gcc, clang with the GCC ABI and clang[1] with the  
non-fragile ABI.

That probably means it's ready for other people to play with.  There  
are almost certainly still bugs, but it's running complex programs for  
me, so they hopefully aren't too major...

[1] The latest version of the runtime now tests if a class declares  
ivars that overlap with the superclass.  Until an hour or so ago there  
was a bug in clang with the GCC ABI that meant that it declared all  
ivars as having an offset of 0, preventing code from starting.  If you  
have a slightly old version of clang, you need to update.
