- As of sbcl-0.pre7.86.flaky7.3, the cross-compiler, and probably
- the CL:COMPILE function (which is based on the same %COMPILE
- mechanism) get confused by

- complaining "function called with two arguments, but wants exactly
- one" about SXHASH-RECURSE. (This might not be strictly a new bug,
- since IIRC post-fork CMU CL has also had problems with &OPTIONAL
- arguments in FLET/LABELS: it might be an old Python bug which is
- only exercised by the new arrangement of the SBCL compiler.)
