Don't know why, I'm no GLib developer nor never worried about it. But how getopt handle arguments "d:e" if you give it "-de"? Does this mean "-d -e" or "-d e"? I'd think that GOption behavior is at least easier to understand. >>> 3) The reason I wanted to migrate to GOption, is that it seems >>> gnome_program_init doesn't eliminate the recognized default arguments >>> such as --g-fatal-warnings, if added.
