You might be able to compile the Sun javax.comm classes.  You would do
this by compiling each .class file separately and then making a `.so'
by linking the results.  Then you would link this .so into your final
application.

This might or might not work.  I don't usually try stuff like this.

If the Sun code has native methods then make sure to compile with
`-fjni'.

There might be a free version of javax.comm around.  I have never
looked.  There isn't one in libgcj, as you noticed.  I don't think
anybody is working on it either.

If there is a free one, and you try it, and gcj can't compile it, then
we would be very interested in whatever bugs you find.  I think it is
important that gcj be able to compile free Java applications.
