  Good luck writing a macro in C to express language functionality for which you don't have the primitives. It's not exactly lisp. Think of C macros as a way to save you some typing and lisp macros as a way to extend the language.

    you can definitely save the chdir and restore it macro.

    setjmp and longjmp are sufficient building blocks for this.
