note: there aren't any actual changes for antlr_cpp besides the version number, it is just bumped for consistency.
The patch for antlr_cpp that was taken from an upstream PR was merged, so it was dropped from the patchset.
* antlr_tool is the grammar compiler * antlr_runtime is the Java runtime (this is also part of antlr_tool) * antlr_cpp is the C++ runtime antlr_tool and antlr_runtime are not built from source, they just repack the downloaded JAR files.
