[chuck-users] ChucK compilation error (still, again?) -- similar to the Ubuntu GCC 4.3 problem

Yeah, that was advertised as the big 10.6 changeover, so I probably
should have thought about it.

How do I specify the 32-bit compile?

Aside: Isn't Ubuntu 64-bit as well? I know very little about Linux,
aside from that we share a command line.

Thanks, Roger.
