we're currently using an antlr C release from Jan-08, there have been numerous bug fixes/improvements since then. Let's upgrade to the latest stable release, which is available at : http://fisheye2.atlassian.com/browse/antlr/runtime/C/dist

Also, let's look into requiring antlr C as a pre-req (for developers, users should still get it packaged with the binary distribution), instead of making it part of the build, hopefully this will remove the need for the hack we added to make it work on 64-bit platforms. We'd need to harvest the antlr libraries and include them in the binary release.

we may also need to upgrade the antlr jar that we keep in our ext dir.

Fixed this a while ago by making libantlr an external dependency.
