The Gnulib portability assumptions 
<https://www.gnu.org/software/gnulib/manual/html_node/Other-portability-assumptions.html> 
say it's OK to add 0 to a null pointer. If you have a real platform 
(i.e., not a pedantic testing framework) where this is an issue, please 
let us know. Otherwise you might look into some way to have clang not 
nag you about this non-problem.
