    diagnostics: Fix bootstrap on 32b Darwin hosts.
    
    The change in r16-7507 misses a cast on the value to pp_scalar which
    leads to a bootstrap fail on 32b hosts where size_t has a different
    declaration from the value.  Fixed by applying the fmt_size_t cast.
    
    gcc/ChangeLog:
    
            * json.cc (pointer::token::print): Cast the value to pp_scalar
            with (fmt_size_t).
