--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-06-29 18:41:33 UTC --- And how do I do that? It would be better to do it for system dirs, not /usr/include, which would also work for cross compilers where the sysroot is not under /usr (this is what I mean about needing to clearly describe your desired semantics, or nothing will happen)
