This indeed works for 0.5.0, but older versions in the tree (0.3.3, 0.4.1) fail without this patch. Either the patch should also be backported there, or the older versions dropped fromt he tree.

Also FIY that these includes are now upstream as part of 0.5.4 ( ), so it might be a good idea to include this version into the tree without the GCC6 patch.
Comment 9 Yixun Lan archtester gentoo-dev 2019-02-12 02:21:02 UTC
I think this bug is obsolete, so let's close it.
