Build completed GCJ, anyone?

[Me Myself and I <stargate7thsymbol@xxxxxxxxxx>]

Is there anyone out there in cygwin land, GNU land or GCJ land who can give me a URL
 
address for a GCJ that will run on windows (default or cygwin mode) that has been been completedly
 
and operates successfully?  I simply can't succeed in building a GCJ, that compiles classes or windows binaries,
 
supports Java 1.6 syntax, that finishes being built (successfully), and that does the job?
 
?
