Private structures and gtk-doc

[Federico Mena Quintero <federico helixcode com>]

Hello,

Right now the gdk-pixbuf module has something like this:

	gdk-pixbuf.h:

		typedef struct _GdkPixbuf GdkPixbuf;
		typedef struct _GdkPixbufAnimation GdkPixbufAnimation;
		typedef struct _GdkPixbufFrame GdkPixbufFrame;

	gdk-pixbuf-private.h:

		struct _GdkPixbuf {
			... bla bla ...
		};

		struct _GdkPixbufAnimation {
			... bla bla ...
		};

		struct _GdkPixbufAnimation {
			... bla bla ...
		};

The gdk-pixbuf.h is public and does get installed; the
gdk-pixbuf-private is just used internally by the library and it is
not installed.

The problem is that gtk-doc is picking up the private structures when
scanning the headers.  I do not want this stuff to show up in the
final SGML files.

How can I tell gtk-doc about this?
