* gmain.h: Removed set_current_panel() since it was never used. * glayout.c (set_current_panel): Made static and renamed from set_new_current_panel(). Removed old toolbar cruft. * gmount.c (get_mountable_devices): Made static. * Makefile.in (ICONS): Added i-floppy.png, i-cdrom.png, i-printer.png. Thanks, Tigert!
