* Source/NSObject:

Browse source 
- Tweaked NSObject to use atomic ops with LLVM as well as gcc (this
		  probably isn't actually needed)
		- Fixed SIGFPE problem on FreeBSD using proper interfaces instead of 
		an asm hack.
	* Removes various mframe things from being compiled when ffcall/libffi is
	used (mframe.m, NSConnection.m, NSInvocation.m)
	* Turned a nested function in make_strings.m into a macro.  

Tested by Gregory - blame him for any breakage...
