Right.

It may not require different ideas, but IMO it benefits from
adopting an approach similar to the posted setjmp version.  Here
is a revision of the code I posted, changed so that it does not
use setjmp()/longjmp() but instead calls main() recursively.  I
think using recursive calls to main to simulate having multiple
functions would make the code more difficult to understand, not
easier.

Note by the way that all calls to main() below are tail calls,
and are optimized away, so there is no stack depth penalty for
this method, unlike using recursive calls to main to simulate
having other functions available.
