Hi all. Well, I finally got around to checking out the problem with compiling legos with gcc 2.95.2. And the good news is, it's not a bug with gcc!!

Sure you can try using just three input/output ports, but eventually you end up scaling back you designs. Of course, you can always buy another RCX to increase the number of ports, which will throw you back $200. Adding a multiplexor is such an easy (...)
