There is another thing, the Java extensions in the C++ FE, which are IMNSHO no longer needed after GCJ removal. Here is a C++ patch that removes that part, bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2016-10-02 Jakub Jelinek <ja...@redhat.com> * doc/extend.texi (Java Exceptions): Remove.
