The article you pointed out suggests that a flex-generated header file would be 
cleaner but it's unavailable. Yet, flex does export a header file which stores 
the start conditions states, although they are enclosed in a #ifdef statement. 

As the article you pointed out appears to be more than 10 years old I believe 
that it may be outdated and can possibly be invalid, as it was possibly 
written in a time where that feature wasn't yet implemented.

So, is it possible to take advantage of the flex-generated header to access the 
start conditions definitions?


Thanks in advance,
Rui Maciel
