23 | # You will slowly go insane if you do not grok the following fact: when | |
24 | # building v3 as part of the compiler, the top-level /target/ becomes the | |
ff66d28f | 25 | # library's /host/. configure then causes --target to default to --host, |
2c839a4e PE |
26 | # exactly like any other package using autoconf. Therefore, 'target' and |
27 | # 'host' will always be the same. This makes sense both for native and | |
28 | # cross compilers, just think about it for a little while. :-) | |
29 | # | |
30 | # Also, if v3 is being configured as part of a cross compiler, the top-level | |
31 | # configure script will pass the "real" host as $with_cross_host. | |

81 | # We're almost certainly being configured before anything else which uses |

84 | # to something unique for us and libjava. Other target libraries need to | |
85 | # find CXX for themselves. We yank the rug out from under the normal AC_* | |
86 | # process by sneakily renaming the cache variable. This also lets us debug | |
87 | # the value of "our" CXX in postmortems. | |
