Someone else suggested that you just need to add stuff to your
struct in even byte multiples.
For your case 2 solutions:
Add your Byte *after* the floats and ints and stuff
-or-
Add your Byte and right after it add another Byte, like so:
typedef struct
{
Byte myNewDataItem;
Byte unused; // this is needed so things belowe are aligned properly
float myfloat;
int myint;
char stringdata[1];
} PackedFoo;
