Port gcc 4.7.1 patches into 3.5.13.1

All, Also noted from the meeting, the current 3.5.13 will _not_ build on gcc 4.7.1. There is _no_ reason not to port the patches to the 3.5.13 code base. All the patches simply cleaned up the code from a syntax standpoint and will not impact it building on earlier gcc releases. The closed bug 979 holds the collection of gcc 4.7 patches that could easily be applied to 3.5.13 to make it gcc 4.7.1 compliant. -- David C. Rankin, J.D.,P.E.
