I verified i386 uses 4 byte, sparc uses 8 byte.
I have no mips handy to test, anyone can run the attached program there?

#include <stdio.h>
#include <inttypes.h>

struct test {
        uint64_t val;
        int dummy;
        char tag;
};

struct container {
        char a;
        struct test t;
};

int main(int argc, char **argv)
{
        struct container c;

        printf("offset of struct test: %lx\n", (long)((char*)&c.t - (char*)&c));
        return 0;
}
