unnamed
> field
> 
> REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3687
> 
> If a C structure parsed by the VFR compiler contains an unnamed
> field, then mFieldName is left uninitialized, which generates
> random data in the VFR compiler output file.
> 
> If the FieldName is NULL, then initialize pNewField->mFieldName
> to a Null-terminated empty string.
