   notation, which is hard to test in my current setup.
 - `stwice.icl`, `twice.icl`: broken (segfault).
 - All others work fine.

+Updated `reverse.icl`, `revtwice.icl`, `sieve.icl` and `copyfile.icl` to
+compile (i.e. use `fromto` instead of `..` and copy library functions in).
+`sieve`, `reverse` and `copyfile` work straightaway.
+
+Got `twice.icl` and `stwice.icl` to work by fixing `thumb2ap.s` (rts
+`4f0223b`). The issue was that the PC was stored with offset 9 instead of
+seven, while a narrow `blx` instruction followed.
+
+There is an issue with `revtwice.icl`; at some point in the garbage collector
+`$r6 == 0x1d1`. This is because the address of `__cycle__in__spine` or
+`__reverse` >> 8 equals `0x1d1`. So somewhere there is an off-by-one error.
+
+I also have the feeling that there should be a `.long 0` right before
+`__reserve` in `_system.s`. Should be checked with John.
