If a macro itself references an undefined macro in the
first part of a lookahead expression, or in the second
part of a lookahead expression when the first part
doesn't have fixed length, then JFlex will give a stack
trace instead of a controlled error message.

Workaround: don't use undefined macros

This bug was reported by Tom Moog.

(fixed in 1.3.1)
