#3 Feature suggestions.

Hi,
Two things
1- Antlr4 (C++ Support)
2- updating compile mode to make grammar error messages linkable.

1. Well, according to https://github.com/antlr/antlr4/blob/master/doc/targets.md , C++ is not really supported yet with Antlr4. But starting with antlr-mode 3.1.1, you can easily set up Emacs for recognizing C++ (I just plan to include that setting if C++ is officially supported...):

(setq antlr-v4-language-list
  '((antlr-java "Java")                 ; +CSharp
      (antlr-cpp "Cpp")          ; my own C++ target for Antlr4
     (antlr-js "JavaScript") (antlr-python "Python2" "Python3")))

1. Huh, has the error format changed with ANTLR 4? Can you attach some output?

ANTLR v4 "Cpp" was added with antlr-mode.el v3.1.5 on 2017-12-15.
