What does your compiler do?. What language is it for?

You may want to search the archives before posting (even if Yahoo
Groups' search feature *sucks* big time). Anyway, here's a post you
may have found that is relevant to your query:
    http://groups.yahoo.com/group/antlr-interest/message/7078

Before you do anything though, have a look at the 2.7.3 release notes
for C# in:
    http://www.antlr.org/blog/CHANGES-2.7.3.txt

This bit from the release notes is relevant. It basically means that
you do not need to override makeToken()/nextToken() anymore in your lexer:
    "c) CharScanner.cs: makeToken(int) now calls setFilename(string)
on newly created tokens"
