Exactly because the version that can run on ARM is not the same as the
one that can run under Windows, which is not the same as the one that
runs under AMD64.

Of course, maybe I'm confused by the table of available binaries (at
http://sbcl.org/platform-table.html), and in reality the latest version
works fine on all supported platforms.
