bitfields, ugh, if you have, say:
...
struct foo {
char c:1;
int b:1;
short a:1;
};
the first byte_size for the first member (c) will be 1, as the "type"
is char, but the compiler combines all of them into a single 4 byte
bitfield, and the '4' only appear when the bit field has type int, in
the above case on the second member.
