I think this is actually a regression in 4.5 and later relative to 4.4.  
It can be demonstrated in older versions using a different test, with 
-std=c99 -pedantic-errors.

#include <limits.h>
struct s { int a: 0? (_Bool)(INT_MAX+1) : 1; };

I'll look at fixing this, since I'm familiar with the integer constant 
expression handling.
