Just Launched: You can now import projects and releases from Google Code onto SourceForge
We are excited to release new functionality to enable a 1-click import from Google Code onto the Allura platform on SourceForge. You can import tickets, wikis, source, releases, and more with a few simple steps. Read More

Can't you run the scripts with SBCL_XC_HOST set to 'lisp -batch' (i.e.
./make.sh 'lisp -batch' or SBCL_XC_HOST='lisp -batch' sh
./make-host-1.sh)? [ or 'openmcl -b' if you're that way inclined?

Neat :) You're very good at finding corner cases... I suppose the
difficulty in this type intersection problem is representing things like
the union of (function (integer) integer) and (function (base-char)
base-char); (function ((or integer base-char)) (or integer base-char))
has lost some constraint information, but is easier to work with (by
some degree, because of the special treatment of FUN-TYPEs) than
(or (function (integer) integer) (function (base-char) base-char)).

Yes, but then any error causes building to fully stop. When I use
'lisp', I can fix bugs and ask to continue compilation from the place
of the fail.
