There was a problem hiding this comment.
Missing the return.
Like I pointed out in other PRs we need have tests which use include files (which need to exist on the filesystem).

I looks like a false positive but using a non-POD variable in a ternary causes it to be copied - see https://reviews.llvm.org/D137205#3939210.
Since simplecpp also supports pre-C++11 standards
std:move()could not be used and I refactored the code instead getting rid of the ternaries.
