# You will slowly go insane if you do not grok the following fact: when

# configure then causes --target to default to --host, exactly like any
# other package using autoconf. Therefore, 'target' and 'host' will
# always be the same. This makes sense both for native and cross compilers
# just think about it for a little while. :-)

# Also, if this library is being configured as part of a cross compiler, the
