See <http://www.open-std.org/jtc1/sc22/wg14/12596> regarding the #if 0 
question.  You could always raise a DR with WG14 or WG21 to try to get 
this question resolved properly.

(4.9 implements the C11/C++11 sets of UCNs allowed in identifiers, but of 
course you need to select the right -std option.  Previous versions didn't 
have that support, just the C99/C++98 sets.)
