Is gcc's __attribute__((packed)) / #pragma pack unsafe?
...c) = 0
offsetof(struct foo, x) = 1
arr[0].x = 10
arr[1].x = 20
p0 = 0xbffc104f

Most common C# bitwise operations on enums
...The idiom is to use the bitwise or-equal operator to set bits:
flags |= 0x04;
To clear a bit, the idiom is to use bitwise and with negation:
