# This script is supposed to be host-agnostic, but unfortunately in testing
# I have found it to be sensitive to the host in the following ways:
#  -  using CCL it gets "Error: Incorrect keyword arguments in (:TEST EQ T)."
#  -  using CLISP it prints "WARNING: cross-compiler type ambiguity" 540 times.
# We could make this use the target SBCL as the new host,
# but that somewhat defeats the purpose.
