AMIDE 0.4.6, and new gcc requirements

gcc 2.95.2 started generating bad code when optimizations were used with this release. I've tried 2.95.3, 3.0.1, and 3.0.2, and the only version that will generate correct code is 3.0.2, so for now on the recommended gcc version is 3.0.2. If you want to use a previous version, see the FAQ on the web page for suggestions.
