I compiled it with both cygwin and mingw.
The .so made with the latter could be used with the PragProg's
single-click installer (the former was to be used with cygwin's
ruby only). What I did was installing mingw, building Ruby with it (just
to get a valid rbconfig.rb), and then *using the new ruby binary* run
  ruby extconf.rb
  make
at this point you cannot 'make install' cause that would put the .so
in the wrong sitelibdir, so I just copied it by hand to the appropriate
place in c:\Ruby (where I had installed the one-click distro). Of course
you can always just modify $:.

One thing that confused me a bit is that in mingw's version #read (for
the serial port object) was blocking whereas in cygwin it wasn't. But I
should have used #sysread anyway.
