[antlr-interest] Bug in the C# runtime with case- insensitive literals

[gsidier]

Hi,

There appears to be a bug in ANLTR/C# when asking the lexer for case-
insensitive literals -- one never gets them !

The source of the error seems to be this line :

CSharpCodeGenerator.java : line # 1253
println("literals = new Hashtable(new 
System.Collections.CaseInsensitiveHashCodeProvider(), null);");


which should be changed to:
println("literals = new Hashtable(new 
System.Collections.CaseInsensitiveHashCodeProvider(), new 
System.Collections.CaseInsensitiveComparer());");

That is to say, the C# code generated for the literals hashtable is 

literals = new Hashtable(new 
System.Collections.CaseInsensitiveHashCodeProvider(), null);

when it should be

literals = new Hashtable(new 
System.Collections.CaseInsensitiveHashCodeProvider(), new 
System.Collections.CaseInsensitiveComparer());

as explained on the Microsoft help page for 
CaseInsensitiveHashCodeProvider (you can look it up on MSDN).

Doing this works for me -- has anyone else stumbled across this 
problem ?


Thanks,
Gregory Sidier.
