Hi

Using ANTLR 3.1, I am rebuilding ANTLR from the sources and got this 
exception
 [myjavac] C:\Program Files\ANTLR\antlr-3.1\codegen\ANTLRLexer.java:61: 
duplicate class: org.antlr.
tool.ANTLRLexer
[myjavac] public class ANTLRLexer extends antlr.CharScanner implements 
ANTLRTokenTypes, TokenStrea
m

Any idea where the problem comes from? or how to fix this?
TIA
Cheers
