# 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. :-)
