Rather than have a flag indicating pass 1 or pass 2, it began to make more 
sense to have two functions.  A few days ago, I had a toggle, i.e. "varb ^= 
true", which was getting set on pass 1 and reset on pass 2.  Today, 
bogolexer had a switch which was getting overridden by the config file, 
i.e. it now needed a second pass.

I hadn't heard of AutoGen or AutoOpts until now.  If they're related to 
autoconf and automake, I'm sure they're wonderfully capable and have a 
horrendous learning curve...
