I was checking AtariAge today and one of the comments there had a really good idea. There should be some way to identify the patch revision in the compiler binary. I'll need to look into how to do that, but it's a really good idea.
Another idea: modify the gcc_installer script to find and use the most recent patches. It would be nice to not have to repackage the installer for every future patch. Also, there's no easy way to tell without unzipping it what patch versions are included in the distribution archive.
Also, there have been a lot of requests for a Windows installer. Can we get away with just installing cygwin and building from there? Can I get the installer to automatically adapt to the build environment? That would be really nice as well.
