| 37 # You will slowly go insane if you do not grok the following fact: when | |
| 38 # building this library, the top-level /target/ becomes the library's /host/. | |
| 39 # | |
| 40 # configure then causes --target to default to --host, exactly like any | |
| 41 # other package using autoconf. Therefore, 'target' and 'host' will | |
| 42 # always be the same. This makes sense both for native and cross compilers | |
| 43 # just think about it for a little while. :-) | |
| 44 # | |
| 45 # Also, if this library is being configured as part of a cross compiler, the | |
| 46 # top-level configure script will pass the "real" host as $with_cross_host. | |
