The following enumerated type definitions packs to one byte as expected in C,
but not in C++:

typedef enum __attribute__ ((packed)) {
        ZERO = 0,
        ONE,
        TWO
} my_enum_t;

The enum will pack as expected if using -fshort-enums, but that doesn't allow
me to pack on a per-enum basis. Neither will the above enum pack as a packed
member in a structure or as a member in a packed structure.

Test case to follow.
