Super cool!

However, in practice it still won't compile and start on Windows... The 
reason is that all paths in the scripts are Unix-like. Cygwin understands 
them properly, but Erlang isn't compiled as a Cygwin application and expects 
regular Windows paths.

The first problem is with the link to hipe_icode_type.hrl: erl chokes on it. 
I copied the file instead, and commented out the lines that create the link, 
because I don't know how to handle this.

The nex problem is when launching dialyzer. I enclosed the definitions 
DIALYZER_OTP and DIALYZER_DIR inside a
    `cygpath -m #`
where # is the value created at setup. I don't have a patch, as it's trivial 
and you might want to handle the OS dependencies in your own way.

After that, I got it up and running!
