This was added somewhere in the 2.7.1 track. It prevents lengthy
(unnecessary) rebuilds in C++ mode. In makefiles I generally use a rule
that runs antlr and touches a little help file. The help file is then used
in following dependencies. This works very well. With a bit of luck it
might work too with your build script ?
