david - apparently windows prefers to dynamically load winsock and a couple other libraries, so I got it all compiling and working in windows, yay!... I tried to minimize the impact on the code: I made a DYNLOAD macro that evaluates to nothing on everything else, but runs the dynamic code if compiled for windows... also, apparently I had been randomly switching between ifdef and ifndef WIN32: so i made most of them ifdefs so it was less confusing...
