[antlr-interest] Odd problem about ANTLR

[lin cyrix]

Hi, everybody,

I try to learn ANTLR (2.7.5) to write a small
calculator. I compose the file calc.g, generating java
class files with ANTLR 2.7.5 (also 2.7.7 with this
problem), it's ok. But when I compile the generated
java files, it fails, and obviously wrong code in it. 

Such as:
(In ArithParser.java)
//////////////////////////////////
	public final double  neg_expr() throws
RecognitionException, TokenStreamException {
		double result = 0;
		
		
		if ( inputState.guessing==0 ) {
			double value = 0;
		}
		match(MINUS);
		value=atom_expr();
		if ( inputState.guessing==0 ) {
			
			result = - value;
			
		}
		return result;
	}
//////////////////////////////////

Can anyone tell me what's wrong ? Is it a bug in
ANTLR, or I make some mistakes in my calc.g ?

Thanks a lot in advance.
Cyrix Lin
