[antlr-interest] Tracking absolute Lexer Position

[Thomas Dudziak]

Have you tried using a special input Reader (java) or fstream (C++)? When
I need absolute (byte) file position, then I simply count the read bytes in the
stream and expose this information to a special token stream which can
store this in the generated tokens if necessary. This way you shouldn't
have problems with lookahead and similar.
