I'm working on fixing the tp-glib introspection stuff to work with g-i master (fdo#30134), and I've come up against the following problem.

I have this code in an (introspected) C file, catering for the rename of TpIntSet → TpIntset (as all the methods are prefixed "tp_intset_"):

typedef struct _TpIntset TpIntset;

/* See fdo#30134 for the reasoning behind the rename of TpIntSet to TpIntset */

/**
 * TpIntSet: (skip)
 *
 * Before 0.11.UNRELEASED, this was the name for <type>TpIntset</type>, but it's
 * now just a backwards compatibility typedef.
 */
typedef TpIntset TpIntSet;

We're (skip)ing TpIntSet to avoid bug #629649 in vapigen.

However, g-ir-scanner seems to ignore the (skip) annotation and the following <alias> element still makes its way into the GIR file:

    <alias name="IntSet" c:type="TpIntSet">
      <type name="Intset" c:type="TpIntset"/>
    </alias>

which causes vapigen pain and discomfort.
