Since nobody else has mentioned it (yet), I will.

You can fake this kind of thing by putting the all the "nested"
routines in one file, and making the "pseudo-globals" statics in that
file. Of course, you can only deal with one level of nesting this way,
and you have to play games with include files and extern to make the
true globals work out, but it can be done.

As for the whole topic, I have to agree with a quote attributed to one
of the designers of Ada: "If you've got data abstraction, nesting is
for the birds."
