That requires Windows to use the Posix configure script.  Doing that
is a large job that is already under way, albeit slowly.  It is a
large job because:

  . neither configure.ac nor the various Makefile.in files, in
    particular src/Makefile.in, currently support the MS-Windows
    build, which needs some special options be used and some special
    commands to be run, as seen in the makefile.w32-in files;

  . the nt/ subdirectory and the parts of the build there are not
    covered at all by configure.ac and Makefile.in files;

  . quite a few of the tests done by configure need to be overridden,
    because the necessary features are implemented only in Emacs's own
    source, not in system headers and libraries; and

  . configure.ac is set up to produce executables statically linked
    against available optional libraries, whereas the Windows build
    loads those libraries dynamically at run time (this is a minor
    annoyance easily fixed in configure.ac, but there are a lot of
    such annoyances, and more are added as we go).

Volunteers to help in this job are welcome.
