Lisp: Bootstrapping SBCL + Caveman on Win 10 64

	The single most important thing is to make and install emacs and gcc to a path without spaces!
	This means, when prompted, to customize your path. Be sane and use c:\ !

	Get and install emacs (unzip to a path with no spaces!)

	Install 64bit MinGW
	Be sure to select x86_64 for the Architecture (not i686!) when prompted

	Install openssl

	// Euclid length because built-in does abs(ddx(x)) + abs(ddy(y))
