I think this is a good idea. It might reduce the number of bugs fixed by git clean -fdx + rebuild. However we have discussed this before and there were some objections.

Unfortunately, not having it makes dependency resolution non-existent, which is a source of subtle bugs, and is a rarely tested configuration, since all Mesa developers likely have it installed. Furthermore some idioms require dependency resolution to work at all, such as making generated files depend on headers. How about failing configure if it's absent? _______________________________________________ mesa-dev mailing list <a href="mailto:mesa-dev@lists.freedesktop.org">mesa-dev@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/mesa-dev" target="_blank">http://lists.freedesktop.org/mailman/listinfo/mesa-dev</a> </blockquote></div>
