 Cody fixed the code and added an appropriate make rule so that the SDL version

-dd0b26b5d6325e8b6fdef1232156c8bb8c66613f. Be prepared for a surprise!
+Due to a terrible design choice of the SDL1 developers something had to be
+changed. As was noted in the log:
+
+```
+The SDL version did not work for a number of reasons. First of all the
+code requires that SDL is defined. Second the path wrong header file was
+included. Third the SDL1 developers thought it would be a great idea
+(but obviously it's a terrible idea) to redefine main() (!!) so that any
+program that uses SDL1 has to have the same args as their definition.
+This program had 'main()' so the error message was:
+
+    thadgavin.c:60:1: error: conflicting types for 'SDL_main'
+    main()
+    ^
+    /opt/local/include/SDL/SDL_main.h:34:14: note: expanded from macro 'main'

+Thus main() was changed to 'int main(int argc, char **argv)'.
