# There is no way to make clang's "argument unused" warning fatal. So when
# configure checks for supported flags, it runs $CC, $CXX, $LD via this
# wrapper.
# Prior to clang v5.1, there was no way to make
# clang's "argument unused" warning fatal. This
# wrapper script that greps for this warning message. Newer clang's have no issues.
#
# Ideally the search string would also include 'clang: ' but this output might
# depend on clang's argv[0].
