There are several typedefs in the GNOME stack that are "hide" their pointer nature:

 typedef struct _GIConv *GIConv;
 typedef struct _GdkAtom *GdkAtom;

And are used:

  gsize g_iconv (GIConv converter, ...);

Currently, they generate something in the gir like:

  <alias name="GIconv" target="none" c:type="GIconv"/>

Which is all sorts of nonsense. The patch I'm attaching does two things:

 * It changes things so they get scanned as normal structures [records]
   but in the .gir it adds the 'disguised' attribute to indicate the
   distinction.

 * The generated typelib is generated as if they were *normal*
   structure references. As if it was:

    typedef struct _GIconv GIConv;

    gsize g_iconv (GIConv *converter, ...);

I think this is is a reasonable approach. The name 'disguised' for the
attribute is a little cryptic (especially since there is no docs of the
.gir format anywhere to add a description to!) but
