== Why is this an issue?

The values which may be represented by a bit-field of length one may not meet developer expectations. Anonymous signed bit-fields of any length are allowed.


=== Noncompliant code example

[source,cpp]
----
struct S
{
 signed int a : 1; // Noncompliant, signed fields require at least two bits
 signed int : 1; // Compliant, cannot be referenced
 signed int : 0; // Compliant, cannot be referenced
};
----


=== Compliant solution

[source,cpp]
----
struct S
{
 signed int a : 2; // Compliant
 signed int : 1; // Compliant, cannot be referenced
 signed int : 0; // Compliant, cannot be referenced
};
----
