This may not be exactly what you want, but it does show you do not need the
identifiers.
typedef struct
{
struct
{
uint8 x:4;
uint8 y:4;
} v;
char name[4];
} PIN;
PIN Pin[] PROGMEM =
{
{ { 1, 2 }, "PC6" },
{ { 3, 4 }, "PD0" }
};
int main(void)
{
PIN local;
uint8 a;
memcpy_P(&local, &Pin[0], sizeof(PIN));
a = local.v.x;
memcpy_P(&local, &Pin[1], sizeof(PIN));
a = local.v.y;
