The runtime doesn't have a version variable of it's own. Yet in normal
(unix) installs there's the antlr-config script, that can be used to
query things like the version include and lib locations.

So you could do things like :

gcc -DANTLRVERSION=`antlr-config --version` .. etc.

And then use preprocessor macros.

If you got antlr in some vendor branch in source control then you
might even introduce a local patch with a version number in the header
file.

Upgrading is pretty much recommended. If you're really fixed on 2.7.1
then you can get a bugfix version from before the ASTFactory reworks
