Bug#759286: smokegen generates wrong cast function for smokeqt

[Matthias Klose <doko@debian.org>]

Package: src:smokeqt
Version: 4:4.14.0-1
Severity: serious
Tags: sid jessie

This causes #759239 and #759205:

In stable, smokegen generates smokedata.cpp(cast), which ends with:

[...]
    case 152: //QXmlStreamWriter
      switch(to) {
        case 152: return (void*)(QXmlStreamWriter*)xptr;
        default: return xptr;
      }
    default: return xptr;
  }
}

in unstable, the function ends as:

    case 155: //QXmlStreamWriter
      switch(to) {
        case 155: return (void*)(QXmlStreamWriter*)xptr;
        default: return xptr;
      }
    case 157: //iterator
      switch(to) {
        case 157: return (void*)(iterator*)xptr;
        default: return xptr;
      }
    default: return xptr;
  }
}

This doesn't look right, and ends with a build error. Removing the 157 case lets
the build continue and then fails further on with
