Vital help needed with GCJ in Windows

[Me Myself and I]

I'm having trouble getting

gcc-java-4.6.2.tar

working under windows 7 mingw32. I have read the instructions with that download,
and find that key scripts just don't want to work.  I have also become aware
of the instructions at

http://rmathew.com/articles/gcj/bldgcj.html

which is too Linux, and GCC oriented (not GCJ).


-Is there a simple set of commands I can use to get my compiler download
built and working?

Can someone please help?
