Debian Wheezy: Building official NVidia driver on 3.16 (amd64) kernel fails to build the DKMS module

Hello,

I am using backports to install newer kernels on my Debian Wheezy OS.

However, trying to compile newest drivers from NVidia on newer kernels fails, and Debian teams blame NVidia, as the answer to the bug report I filled in indicates:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763629

Logs are attached in the Debian bug report.

What to do?

It works fine under Liquorix: http://liquorix.net/ / https://github.com/zen-kernel/zen-kernel/tree/3.16/master

Try to diff-it somehow.

I am using Debian Wheezy with backported kernel from official repository.

How could you diff sources from different distros? oO
