The output of emerge _is_ what really happens, as it's the output from |
| 15 |
the build system (auto* tools and gcc) |
| 16 |
Consider the first "configure" you find: |

./configure --prefix=/usr --host=i686-pc-linux-gnu |

--mandir=/usr/share/man [......] --without-big-tables |

|
| 36 |
for example "--build=i686-pc-linux-gnu" it's not directly setted by the |
| 37 |
ebuild (speaking of ebuild code, not the portage one) |
| 38 |
|
| 39 |
and this other (sub)configure, it also contain option not setted by the |
| 40 |
ebuild. |

As a final ans side note, it's gentoo policy that the ebuild set all the |
| 51 |
configure options avaiable to it (but it's not _mandated_ to leave the |
| 52 |
user the possibility to select them via use-flags). |
