How does a C struct ignore internal order for the compiler?

Question

For example, we have two structures:

struct type1 {
    int  t;
    char c;
};

struct type2 {
    char c;
    int  t;
};

At what point does the C compiler ignore the difference in order and set them as the same structure? And How?
