un named bit fields

[sophia]

Dear all,


what exactly is the purpose of un named bit field such as this

struct
{
int first_bit : 1;
unsigned : 14;
int last_bit : 1;
} bf;

Spacing. Presumably this structure maps onto some externally defined
layout (given the details of how bit fields are implemented on this
particular implementation) , and the ":14" defines a range of 14 unused
(or uninteresting) bits.
