I'm aware of what configure.in does. This is what I think it should do.  
Rather that unconditionally disabling libgcj on a given target, it 
should instead specify a default set of arguments for the 
--enable-languages option.

Right - there is some hope of libgcj working on most platforms, its just 
that nobody tests them often enough for us to be able to say that they 
definitely work. Irix is an interesting case because it does seem to 
work for some people but not others (due to the link command line length 
thing, which we never quite solved) on seemingly the same OS. Perhaps 
due to different patch levels of Irix or something. In this case it 
would be best to disable by default, but make it easy to enable with an 
explicit "--enable-languages=java" which would override any default 
setting in the configure.in. Specifying one command line option to all 
of java seems a lot less painful to me that having to mess around with 
configure.in all the time.

And, if we are going to enable java by default then we really need 
"--enable-threads" and possibly "--enable-shared" by default also. If we 
don't or can't do that, then I think its actually good that we require 
--enable-languages in order to draw attention to the need for these 
additional arguments.
