I finally got DSL at home, and got my linux box configured, so I can work on fastjar again (finally.) I integrated the GNU gcc patches to fastjar, so now it should compile better on various systems, as well as make it easier for the gcc team to use fastjar.
I just tested fastjar compilation under NT 4.0 Using Cygnus's bash shell. Everything seems to work just fine.
The fastjar code has been checked into the main gcc branch, and is being actively patched by the gcc team.
