svn head as of yesterday.

I hope I got around it changing Makefile.cross-linux-mingw like this:

# commands

HOSTSYSTEM=i586-mingw32msvc
CHICKEN=chicken



But I'm not yet there that I have tried the result.

Well, in the second step I tried to build a cross compiler to create
windows binaries from the chicken host.  Eventually I tried
mingw-chicken-setup - the cross compile thingy - to set up easiffy.
Since that's a host extension, I passed the -host-extension option, but
that one did *not* pass the "-host" to csc!

Therefore I changed the define-macro as above.  Currently there is this:

(define-macro (compile . explist)
  `(run (csc ,@explist) ) )

That means the -host-extension option is ignored.
