The build gets well along and then I get error below. Below is the configure output and a snippet of the end of the console output where the build fails.
The problem doesn't look like it's due to your setup, it looks as
though GCC 4.2 had some invalid code which is rejected by the stricter
GCC 4.8 compiler.

What should work, but is quite tedious, is to use 4.8 to build
something intermediate, say 4.5, and use that to build 4.2.
If that still fails, build an extra intermediate step, or steps.
