[antlr-interest] Compile errors with CSharp2 Target

[David Daeschler]

Just my two cents here

I also had an issue until I manually compiled the latest version of the
CSharp3 runtime to work with the current 3.3 ANTLR release. I had code
generation issues when I tried to use the prebuilt DOT-NET-runtime-3.1.zip
with the current ANTLR 3.3 release.

Hope this helps.
