sum of all holes too.

51a8d81527 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.

a4e260fc1a Grr, another fix for bitfields, this time for a sequence of 
bitfields, i.e. the offset changes from one bitfield to another.

e45d94f9de Fix bitfield accounting, as I was assuming that the first field would be 
at the 0 offset, but its not, so just look if the last member was in a
bitfield.

e748ac69c3 Print the diff when the sum of the member sizeofs + the sum of the 
holes is not equal to the size of the struct:

struct task_struct {
<SNIP>
}; /* sizeof struct: 1312, sum sizeof members: 1279 */

/* BRAIN FART ALERT! 1312 != 1279 + 25(holes), diff = 8 */

it doesn't have a return value, i.e. it "returns" void.

cc701e54a3 Check if the sum of the struct member sizeofs plus the sum of all the holes 
found is equal to the sizeof of the structure and emit a "BRAIN FART ALERT!" if
this assertion fails, good news is that no such brain farts ocurred so far :-)
