after some fiddeling, the following does work for me under Win XP,
cygwin, using the Enthought Python. cygwin python does return "posix"
for "os.name" so the 'argv = [os.environ['COMSPEC'],'/C']+argv' part
could be OK:

This version also works for me on Solaris and Linux with Python 2.2.1,
and distutils from 2.3.3 replacing the original one.
