C89 Nolib Save

a very simple experiment to see if i can make a game in C89 without the standard library.

Windows example building with GCC:

• only compile game.c, it includes everything else.
• use the equivalent of -nostdlib and -std=c89

gcc game.c -nostdlib -std=c89 -e _start C:\Windows\System32\user32.dll C:\Windows\System32\Gdi32.dll C:\Windows\System32\kernel32.dll

For non-Windows, a different Platform implementation must to be defined, which in turn should call nb_init and nb_step.
