UCPP: cross-platform C++ toolchain

[AntiSleep]

Think I sorted out the problem after reading through ucpp-setup. My first installation failed to download the support files since curl wasn't installed. After I installed and re-ran, the setup script thought everything was already installed because the directory was present - even if it was mostly empty.

Using the gccdist link in the setup file I think has gotten me everything I need. If all else fails I can just rm the whole .ucpp directory and re-run ucpp setup.

I guess the lesson for future generations is, if you have a problem during setup, make sure and delete the '.ucpp' directory before retrying.
