[antlr-interest] Problem with C target output

[Kamil Burzynski]

Jim,

  It seems, that start and stop fields in ANTLR3_COMMON_TOKEN_struct are 
not just plain offsets since beginning, but they are pointers?
Therefore if you need offset you need something like $foo.start - 
$foo.input.data ? Also, this influences error messages being produced by 
your target: while in Java the same error produces nice offset in the 
error message, C target does print some pointer value, which is 
unreadable.. Can we fix it in the next version?

Excuse me for no example (as I have none handy at the moment). If my 
description above is too messy and you will need example, I'll try to 
get one for you.
