Eli has some work in libjit to make it work better on Windows.

I haven't done anything recently but I do have a work-in-progress patch
to improve the calling convention; and this would also provide
infrastructure to allow more direct calls to C and for inlining.  Not
sure when I will finish that.

Yes, el-compilador is pretty unfinished.  I think it should support
all of elisp in the front end and in the optimizers; but the C back end
is quite incomplete.

I wrote a second compiler, though, that just compiles from bytecode to
C.  This one is more complete, see my post about it from sometime in the
last month or so.  IIRC wiring it up to the build was the remaining
difficulty.
