# You will slowly go insane if you do not grok the following fact: when
# building v3 as part of the compiler, the top-level /target/ becomes the
# library's /host/. `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 v3 is being configured as part of a cross compiler, the top-level
# configure script will pass the "real" host as $with_cross_host.
#
# AC 2.5x sets target_alias iff the user specified --target, but we use it
# everywhere, so we set it here just to be sure. In AC 2.13
# AC_CANONICAL_TARGET was known as AC_CANONICAL_SYSTEM.
