Thanks, Phil,
I'm compiling the code for which I wrote the build system and I have never heard
of this flag, so it is definitely not a flag added by what I wrote. That build
system only adds to the existing flags whatever compiler is using, which is
mpic++11, a wrapper for bgclang. Grepping for qlang from `mpic++11 --help`
yields nothing and I cannot find a manual page. I'm not sure how to remove that
argument from the list.
