* dw2gencfi.c (CUR_SEG, SET_CUR_SEG, HANDLED, SET_HANDLED): Define.
Use throughout in place of #if SUPPORT_FRAME_LINKONCE. (struct fde_entry): Rename cseg to cur_seg. (cfi_change_reg_numbers): Remove ATTRIBUTE_UNUSED. (get_cfi_seg): Likewise. Use if (SUPPORT_FRAME_LINKONCE) rather that #if SUPPORT_FRAME_LINKONCE. (cfi_finish): Likewise.
