libobjc2 C++11 compatibility fix.

[Maxthon Chan]

Here is a small patch I made so that libobjc2 can be built on environments 
where -std=c++11 presents in CXXFLAGS.

The last time when I built libobjc2 linking against libsupc++ with clang SVN 
(itself is built with C++11 enabled, together with lldb and linked against 
libc++) enabling C++11, I hit some issues and fixed with a fix like this. Now I 
publish this patch.

My release of this patch is public domain software.
