In a few places we still use the good old: sizeof(var) / sizeof(var[0]) sizeof(var) / sizeof(int) The G_N_ELEMENTS() macro is preferred though. In a few places we don't link with glib, so provide the macro definition. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Kristina Hanicova <khanicov@redhat.com>
