    #define ARGV argv

    Why not just do this instead:

    main (int argc, char *ARGV[])

    Also, another minor quip: the C program is not valid C in either C89 or C99. It's not valid C89 because it uses '//' for a comment, and it's not valid C99 since it introduces main() without declaring the return type. C89 defaults to int if you don't declare the type (both for functions and variables, which can be fun), whereas this behaviour is undefined in C99. Normally, I don't follow the anal-retentive lingual purists, but I think this situation calls for this.

    But yeah, this is pretty cool.
