  # test.h
  #define GTK_TYPE_BIN                  (gtk_bin_get_type ())
  #define GTK_BIN(obj)                  (G_TYPE_CHECK_INSTANCE_CAST ((obj), GTK_TYPE_BIN, GtkBin))

  c2nim --nep1 test.h
  const
    GTK_TYPE_BIN* = (gtkBinGetType())
  
  template gtk_Bin*(obj: expr): expr =
    (g_Type_Check_Instance_Cast((obj), gtk_Type_Bin, gtkBin))

  c2nim test.h
  const
    GTK_TYPE_BIN* = (gtk_bin_get_type())
  
  template GTK_BIN*(obj: expr): expr =
    (G_TYPE_CHECK_INSTANCE_CAST((obj), GTK_TYPE_BIN, GtkBin))

  I considered using the latest c2nim version for prepairing the gtk 3.20 related wrappers because it has bitfield support and is generally a bit smarter. Because for that I would have to fix large parts of my scripts, I considered --nep1 option at the same time. But as you can see nep1 can really generate a lot of problems. gtk_Bin as template name is a bit strange, but that is not a real problem. But GTK_TYPE_BIN as function alias and in the template gtk_Type_Bin symbol for that alias gives some trouble. Of course I can remove the gtk prefix, but the problem would still exist. The output without nep1 is really more nice -- the template name is upper case, but that is not difficult to fix, I did that for the 3.15.xx wrappers.

  So we should be really careful with nep1!

  Run

  c2nim --nep1 --skipcomments --skipinclude ggg.h

  Are these 3 empty lines above const intended?
