| I'm not sure what you mean by that.  It's a public constructor;

I mean that it is not a standard constructor, and it is not a
constructor I documented as a GNU extension.  The fact that it is a
public constructor is not, by itself, a documentation that it is a
standard constructor or a constructor that users should use.
