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

+# 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.  :-)
