[antlr-interest] Linear approximate lookahead question

due to linear approximate lookahead the following grammar gives a
non-determinism warning:

a: z S P;
b: z T Q;
z: P (T P)*;

because z can be followed by (T Q | S P) which leads to a possible T P
in the approximation.

How can I resolve this, besides pasting z into a and b rules? Sorry, if
this has been asked before.
