See lines 95-100 in scan.l:
* OK, here is a short description of lex/flex rules behavior.
* The longest pattern which matches an input string is always chosen.
* For equal-length patterns, the first occurring in the rules list is chosen.
* INITIAL is the starting state, to which all non-conditional rules apply.
* Exclusive states change parsing rules while the state is active. When in
* an exclusive state, only those rules defined for that state apply.
