Why are you spreading misinformation? The GCJ runtime library does not use the LGPL. It uses the GPL, with an exception that permits linking against proprietary code. This is very friendly licensing IMO, and the FSF bashing is not warrented.

No, you don't have to use cygwin. There's a mingw32 version that will let you build real cygwin-less binaries. See http://www.thisiscool.com/gcc33_mingw.htm

People are even building ActiveX controls with gcj: http://www.xwt.org
