[antlr-interest] Ambiguity with similar token with different length ...

ANTLR has a tedious behavior which I wonder if there is anyway to go
around:
let say in my option I have: {
k = 2;
}
and have 2 lexer tokens like:
LT: "<=";
LE: '<';
I am sure that my grammar would have ambiguity warning while
generating with 'java antl.Tool', in fact if I ever have (ever in the
parser or the lexer, even if 'k' is big enough) 2 rules which have
similar begining and different length I would have such warning even
if there is no real ambiguity.
How to solve this problem ?
I mean how should I write my rules, or which tag should I employ for
writting warning free grammar ?
