Hi,

the bug is very clear: in C++11 we reject the testcase becausenull_ptr_cst_p returns 'true' for 'false', whereas [conv.ptr] iscarefully worded in terms of integer literals not boolean literals. Theobvious fix, using == INTEGER_TYPE instead of CP_INTEGRAL_TYPE_P,appears to work well.


Tested x86_64-linux.

Thanks,
Paolo.
