OK, I managed to build everything with the released 3.1 now. There was
some environment variable that still pointed to the b2 version in my
build system. Deeply sorry for all the noise concerning it not building.

Yet with the released 3.1 I still get 0 for the token indexes. Here's
how I get at the indexes:


ANTLR3_BASE_TREE_struct*        mAST;
ANTLR3_COMMON_TOKEN_struct*     mToken = mAST->getToken( mAST );
unsigned                        index = mToken->start;

but I also tried 

unsigned                        index = mToken->getStartIndex( mToken );

Is this the correct way of getting at the token indexes? If not, can you
point me to the functions in the documentation that I need in order to
get the correct indexes?

Thanks,

Sven
