That only solves the issue in the master branch (where there is no Jenkins
issue currently, because of differences between the branches). All the
affected patches are in release-4-6.

others) is only added to the C compilation flags, but nvcc gets its flags
from the C++ flags. So these warnings are not silenced in CUDA code when
compiling with gcc 4.8.

The reason why it has started occurring now is that previously, the gcc 4.8
build on the GPU host was built with GMX_GPU=OFF, but it has now been
changed to build with CUDA 5.5. You can see this if you compare a
successful build and a failing build for one of the affected patches.

Best regards,
