Tangentially, I'd like to know how C fits into your application. 
Given the computational workload in expressing the algorithm suggested by the 
GA as C,
then all the effort of compiling that C to object code, I'd be surprised if you 
saw any usefull
gain for using C. 

You'd be better off generating an Intermediate code from the GA, and then 
running that through register assignment.
