If it's C++-only then it would need to be in g++.dg.

The way we handle GCC-specific types in checking these formats is that the 
code using these formats has to define typedefs which the format-checking 
code then looks up.  In most cases it can just look up names like 
location_t or tree, but for HOST_WIDE_INT it looks up 
__gcc_host_wide_int__ which the user must have defined as a typedef.  
Probably that's the way to go in this case: the user must do "typedef 
vec<int> __gcc_vec_int__;" or similar, and the code looks up
