Working on the build system.

Writing a script which downloads every release of GCC from the latest back to 4.1.2, building the version in question and then using that build to *build itself* again (i.e. so I have the given version of the compiler used to build the given version of the compiler, just as in the official releases).

I’m then going to build, test and benchmark against all versions, for every release.

I need to do the same for clang, and that’s more pressing, because the test app goes into a permanent loop with clang 3.8.0 in one the elimination layer freelist tests. It might be a compiler issue, or it might be an EA bug.

Using multiple compilers is a Bloody Good Thing.
