You haven't said on which OS this is supposed to run. I am just guessing here 
that it is a POSIX compatible one (i.e. Linux, OS X). If that's the case, you 
just might use fork() which you can use to create new processes on Unix 
flavored OSes. This function is kind of "cloning" the original process that 
called fork(), that is the new process(es) will have (almost) the same data in 
memory as the original process had when it called fork(). So that's probably 
easier than what you were trying to achieve by dealing with environment 
variables.

That's a very basic programming question though, not really related to Bison.
