[antlr-interest] Grammer wont compile, any pointers?

[rhalin]

I'm having almost this exact same problem.  Antlr 2.7.2 on Slackware 
Linux running KDevelop.  Grammer compiles and links fine in Visual 
Studio 6 in Windows (antlr 2.7.1).  The examples also compile fine.  
I'm linking against the antlr.a library.  Since the examples compile, 
I'm thinking I'm missing a compiler flag somewhere, any ideas?  Any 
help would be appreciated.
