Hi Mark,

Thanks for your help, but now I am confused!!

It seems to me that I am living rather far from the edge, I am running the
most recent LTS version of the most popular Linux distro.

if I understand you correctly, the maintainers of nvidia-cuda-dev (
7.5.18-0ubuntu1) in 16.04 must have willfully hacked
/usr/include/host_config.h,
just to fake gcc 5 compatibility?

cheers

Sjoerd
