Ric, 

I found these guys very responsive:

    rhug-rhats@sources.redhat.com

What they showed me is that a default install of
gcc3.3 on RH7.2 isn't gonna cut it.  It does not
overwrite /usr/bin/gcj or libgcj.so

You don't want to see this!

    $ ls -l /usr/lib/libgcj.so.2.0.0
    -rwxr-xr-x    1 root     root      
    8405787 Sep  6  2001 /usr/lib/libgcj.so.2.0.0


green@redhat.com is an antlr user, and he might
upload an RH9 executable or help you make an rpm.
I'll cross-post.

Er, that would be

So sorry.

FWIW, I used antlr on regular basis with gcj (and gij).

If I could change one thing about antlr, I would try to make a cleaner
separation between the build- and run-time classes.  Right now they are
all in one package.  Moving the runtime classes into a different
package, say antlr.runtime, would make life easier for gcj users.  Once
done, we could build and use lib-antlr-runtime.so.  There's no obvious
way to build nice shared libraries without this separation.  You either
put everything into one .so, or you do some thing weird.

BTW - I was looking at how ant uses antlr.  It looks like it spawns a
new java process.  Why does it do this instead of just loading the
classes and running in-process?

Well, to be clear, these days I just run antlr with "gij" instead of
"java", and then I link native versions of the runtime classes into my
app.  Here's the list...
