-# The value of SBCL_XC_HOST should be a command to invoke the
-# cross-compilation Lisp system in such a way that it reads commands
-# from standard input, and terminates when it reaches end of file on
-# standard input. Some suitable values are:
-# "sbcl" to use an existing SBCL binary as a cross-compilation host
-# "sbcl --sysinit /dev/null --userinit /dev/null"
-# to use an existing SBCL binary as a cross-compilation host
-# even though you have stuff in your initialization files
-# which makes it behave in such a non-standard way that
-# it keeps the build from working
-# "sbcl --disable-debugger"
-# to use an existing SBCL binary as a cross-compilation host
-# and tell it to handle errors as best it can by itself
-# (probably by dying with an error code) instead of waiting
-# endlessly for a programmer to help it out with input
-# on *DEBUG-IO*
-# "lisp -batch" to use an existing CMU CL binary as a cross-compilation host
-# "lisp -noinit -batch"
-# to use an existing CMU CL binary as a cross-compilation host
-# when you have weird things in your .cmucl-init file
-# "openmcl --batch"
-# to use an OpenMCL binary as a cross-compilation host
-# "clisp"
-# to use a CLISP binary as a cross-compilation host
-#
-# FIXME: Make a more sophisticated command line parser, probably
-# accepting "sh make.sh --xc-host foolisp" instead of the
-# the present "sh make.sh foolisp".
-# FIXME: Tweak this script, and the rest of the system, to support
-# a second bootstrapping pass in which the cross-compilation host is
-# known to be SBCL itself, so that the cross-compiler can do some
-# optimizations (especially specializable arrays) that it doesn't
-# know how to implement how in a portable way. (Or maybe that wouldn't
-# require a second pass, just testing at build-the-cross-compiler time
-# whether the cross-compilation host returns suitable values from
-# UPGRADED-ARRAY-ELEMENT-TYPE?)
-# FIXME: --noprogrammer was deprecated in sbcl-0.7.5, replaced by
-# --disable-debugger. We still use the old form here because the
-# change was not preannounced, and it would be rude to make our new
-# version of SBCL unbootstrappable by immediately prior versions.
-# But in a year or so the --noprogrammer here can change to
-# --disable-debugger (and the deprecated --noprogrammer support can
-# go away completely).
