INT is a lexer rule and should not be in a tree parser grammar; 
Take that out and try again, if that does not work, make sure you are
using a current version of ANTLR. 
ASTLabelType is not CommonTree for C, it is pANTLR3_BASE_TREE. 
Make sure your token vocab file exists. 
Make sure you read:  http://www.antlr.org/api/C/index.html  before
trying to use the C API. 
Make sure that your file name is the same as your tree parser name;
