static-vectors dependency not supporting 64-bit windows

[dwringer]

I realize there's only a small minority using a system like this on a Windows machine, but loading the package :ningle from quicklisp results in some CFFI grovel errors related to the static-vectors package not supporting Windows' 64-bit architecture. I told the debugger to "Accept and continue", at which point I was successful at following the basic tutorial for the ningle package and serving basic text on a couple of ports. I'm not sure what is or may be affected by having continued past the static-vectors package errors, or if a workaround is worth pursuing, but I thought I would bring it to your attention. Great work, and thanks!
