I installed the GCC 4.8.2 a couple of weeks ago. The installation process went well and I have GCC 4.8.2 at my Ubuntu system (12.04 64 bits). Now GNU just released the newer version 4.9.0.
My question is: Is there any way to upgrade my GCC to 4.9.0 without doing all process: configuration, building, checking and installation from scratch? Also, please tell me what is the benefit/purpose of gcc-4.8.2-4.9.0.diff.gz file? Is it like script/patch file to upgrade my compiler?
FYI, I don't have any plan to have two different versions of GCC at my system.
