[antlr-interest] antlr 3.4 beta 4 (release candidate)

[Mu Qiao]

There is a rule that might take longer time. But it won't take longer
than 30 seconds to get the error. I used
antlr-master-3.4-beta4-completejar.jar and this is the command I used:
java -classpath antlr-master-3.4-beta4-completejar.jar org.antlr.Tool
-Xwatchconversion libbash.g
