But #undef and #include in such an #ifdef block are somewhat unusual, and in this case they seem to be additions, not code movement. Can you explain what's going on here? _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
