A 'pre-built windows binary' of what?

You can easily ship a DLL or .exe for use on Windows: just make use of 
configure.win and/or Makefile.win.  If you have a Makefile.win it will 
override the normal procedures for directory src.  OTOH, shipping 
something in exec will be installed everwhere.

Watch out for sub-architectures: 'Windows' is in fact two platforms.  We 
have over the years seen a lot of problem with people shipping 64-bit 
Windows binaries: 32-bit Windows does not recognize those.
