In my code I want to store default values in a const struct, but I want to use the member names during initialization to prevent future bugs in the case of a typo. ("designated initializer list" is what that's called, right?)

struct
{
   u32 serial_number;
   u8 model;
   u8 mfg_year;
   u8 mfg_month;
   u8 mfg_day;
} info;

const struct info x
{
   .serial_number = 0,
   .model = 0,
   .mfg_year = 11,
   .mfg_month = 3,
   .mfg_day = 1
};

But I get

const struct info x
{
   0,
   0,
   11,
   3,
   1
};

What are my options?
