Compiling and linking with G++

Greg --

You might take a look at the Makefiles I used to compile rtcmix~ for
windows (source is here, down towards the bottom of the page):

http://rtcmix.org/rtcmix~

I was able to use g++ to compile the main RTcmix code and then drag
it into the rtcmix~ object. It's pretty grungy code, though.
