changed. Switch from int to short, to match struct sctstr members sct_item and sct_avail. Symbolic indexes for struct bp member bp_item[]: (BP_NONE, BP_CIVIL, BP_MILIT, BP_SHELL, BP_GUN, BP_LCM, BP_HCM) (BP_MAX): New. (bug_key): Use them. Values are now array indexes, not indexes + 1. (bp_get_item, bp_put_item, bp_set_from_sect): Update for changed bud_key[].
