19 | # You will slowly go insane if you do not grok the following fact: when | |
20 | # building v3 as part of the compiler, the top-level /target/ becomes the | |
ff66d28f | 21 | # library's /host/. configure then causes --target to default to --host, |
2c839a4e PE |
22 | # exactly like any other package using autoconf. Therefore, 'target' and |
23 | # 'host' will always be the same. This makes sense both for native and | |
24 | # cross compilers, just think about it for a little while. :-) | |
25 | # | |
26 | # Also, if v3 is being configured as part of a cross compiler, the top-level | |
27 | # configure script will pass the "real" host as $with_cross_host. | |
