# Newer versions of clang++ promotes "unused driver arguments" warnings to
# a fatal error with -Werror, causing build failure. Since we use multiple
# compilers on multiple systems, this can easily happen due to settings for
# non clang++ environments that could be just ignored otherwise. It can also
# happen if clang++ is used via ccache. So, although probably suboptimal,
# we suppress this particular warning. Note that it doesn't weaken checks
