For instance, "ppc i386". If the current machine 11# isn't in the list, it will (effectively) be added. 12# FIXME: HOSTS is not used in this script. Use it or Remove it. 13HOSTS="$1" 14 15# The second parameter is a space-separated list of the architectures the 16# compilers will generate code for.
