This is great news ! (wow -- imitating chronoline.c -- not for the faint of
                      heart)

GINT_TO_POINTER(x) is GLibese for ((void *)(x))

I guess I could be more helpful if you could point me at some context... (I
suspect it's related to the possibility to have the same underlying type
appear several times on a sheet with different defaults, eg: in the GRAFCET
sheet, Step and Initial Step are the same object, but with different
initialisation parameters. IIRC, the "variant" value is passed as a "void
*", so as we need to pass an int, we cast it using GINT_TO_POINTER (and
GPOINTER_TO_INT)).
