This was a machine running SunOS 4, which we no longer support. It had an odd display controller and a compiler with issues that required workarounds. Those compiler issues aren't an issue in today's world, so we don't need to keep the workarounds present for reference. It had a bit of inline assembly, but that is still present in other files for other platforms.
