I actually have patches for most of the issues, and have previously posted them at http://gcc.gnu.org/PR53348#c7 but David Edelsohn took no notice of them. If you're interested, I'll be happy to update the patch for current SVN. At any rate, I'll let you know how the build goes. This machine isn't exactly a speed demon, so give it a day or three....
