I am interested in the syntax convention for BitFields in C++ and if different methods of naming variables need to be accounted for in the number of allocated bits.

```
union BitField32
{
    struct {
        unsigned int a : 1;
        unsigned int b : 1;
    };
    unsigned int data;
};
BitField32 Flags;

```

vs

```
union BitField32
{
    struct {
        unsigned int a, b : 1;
    };
    unsigned int data;
};
BitField32 Flags;

```

Does naming the variables in the bottom example require the use of two bits or are they allocated a single bit
