unsupported GNU version! gcc 4.9 and up are not supported!

Trying to recompile everything for Fedora 23.

/usr/local/cuda-5.5//bin/..//include/host_config.h:82:2: error: #error -- unsupported GNU version! gcc 4.9 and up are not supported!

# gcc --version

See from my mirrors there is a cuda 7.5:

cuda-cli-tools.x86_64      7.5.18-2.fc23  negativo17-nvidia
cuda-devel.x86_64          7.5.18-2.fc23  negativo17-nvidia

cuda.x86_64                7.5.18-2.fc23  negativo17-nvidia

Any chance we can get cuda 7.5 support?

@MikeyCarter Just do :
sudo apt-get install gcc-4.8 g++-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50
