[antlr-interest] question on C target generated code

Greetings!
I'm trying to put together a grammar targeted at C, but am running into
a problem at compile time. Here's a snippet of my code:
firstlet = (pANTLR3_COMMON_TOKEN)LT(1);
MATCHT(LETTER, &FOLLOW_LETTER_in_cor145);
if ( !(firstlet->getText(firstlet).equals( "C" )) )
{
CONSTRUCTEX();
EXCEPTION->type =
ANTLR3_FAILED_PREDICATE_EXCEPTION;
EXCEPTION->message = "$firstlet.text.equals(
\"C\" )";
EXCEPTION->ruleName = "cor";
}
I get the following error message in gcc:
ReccoParser.c: In function `cor':
ReccoParser.c:1490: error: request for member `equals' in something not
a structure or union
It's clear that firstlet is a pANTLR3_COMMON_TOKEN, and the getText
function returns a pANTLR3_STRING. But the ANTLR3_STRING structure
doesn't have an equals member - the closest thing it comes to it is a
compare method. I'm left scratching my head. Could someone enlighten
me as to what I'm missing?
Thanks!
Warren Madden
