[antlr-interest] problems building antlr using antlr.build.Tool

[John Clayton]

I think I may have solved my own problem (it's reaching my code where  
it's encountering errors ;-) here by setting CLASSPATH in the environ  
rather than on the command line.  I guess the tool might look for that  
when it invokes the compiler?  Could be.  Still, any feedback is  
appreciated.
