Look at QP-Nano at http://www.quantum-leaps.com ; it's been ported to 
AVR using another compiler, but I ported the full version to avr-gcc easily.

It provides all the infrastructure for multiple state machines; your 
state machines are implemented as a single function per state which 
typically has a switch on the event type.

I don't think that a code generator would do any better than you could 
do with this framework, and it's not been my experience that maintenance 
of such programs is at all difficult.
