fix Makefile and README.md for 2000/natori
There was an attempt to get natori.c to compile.
We moved the 2 includes to the compile line
restoring the code as a 1-liner.
We forced the types of args iun main to conform to
bogons introduced by the ANSI-C committee.
Nevertheless, the code still fails to compile:
assignment to cast is illegal, lvalue casts are not supported
This will be a TODO fix for later.

The ANSI-C committee, among their multiple misdeeds, broke perfectly
|
||||||
|
fun C programs by making it intractable for them to declare their
|
||||||
|
own non-traditional prototype for main(). We have had uglify this
|
||||||
|
program in order to try and prevent C compilers form failing to
|
||||||
|
compile due to the unusual arg types of the main() function.

This program outputs a rough image of the moon in its current phase.
