+# 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

+# 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
