17 ;;; FIXME: Double colons are bad, and there are lots of them in this
18 ;;; file, because both dump logic in SB!C and load logic in SB!IMPL

20 ;;; moved into a single package, perhaps called SB-LD.
22 ;;;; fasl dumper state
24 ;;; The FASL-FILE structure represents everything we need to know
25 ;;; about dumping to a fasl file. We need to objectify the state,
