[Boost-build] Fixing intel-darwin linker symbols

Hi,

The attached patch fixes these undefined symbols

__ZNSt15basic_streambufIwSt11char_traitsIwEE8overflowEj
__ZNSt15basic_streambufIwSt11char_traitsIwEE9pbackfailEj

when building with the intel-darwin toolset.  The fix just defines - 
D__WINT_TYPE__=int to match the behavior of the darwin toolset.  I  
realize this patch is unorthodox in that it patches the c and c++  
build actions but this approach seems simpler than adding a new macro  
to Boost.config and going that route.  I'm all ears if someone has a  
better idea on how to patch this.

Any objection if I commit this?
