I generated new gtk_enums.defs, and it turned out that there was an
empty definition:

;; From /home/marko/cvs/gnome2/gtk+/gtk/gtktreeprivate.h

(define-flags-extended TreeViewFlags ... ;; this one's ok

(define-flags-extended 
  (in-module "")
  (c-name "")
  (values
    '("toggle" "GTK_TREE_SELECT_MODE_TOGGLE" "1 << 0")
    '("extend" "GTK_TREE_SELECT_MODE_EXTEND" "1 << 1")
  )
)

which should obviously be:

(define-flags-extended TreeSelectMode
  (in-module "Gtk")
  (c-name "GtkTreeSelectMode")
  (values
    '("toggle" "GTK_TREE_SELECT_MODE_TOGGLE" "1 << 0")
    '("extend" "GTK_TREE_SELECT_MODE_EXTEND" "1 << 1")
  )
)

which solves that part.

This went away too.

Actually how could that happen? GtkTreeSelectMode is not new.

I added _CONV_ENUM(Gtk,RecentFilterFlags) to tools/m4/convert_gtk.m4
and updated the prefix, but I still get that error.
I do:

_WRAP_ENUM(RecentFilterFlags, GtkRecentFilterFlags)

but running gmmproc with that line or commented doesn't make
any difference in output(?).

Btw what do you mean by this comment (in convert_gtk.m4):
"# Enums: TODO: It would be nice if gmmproc knew about these
automatically." ?
