This latest patch that Chris has sent out fixes the issues I've been encountering. I can build gcc-4.4.5 without problems. Also, the portion of Openmotif that was having issues with page faults is working correctly. Let me know if you still would like to see the path names for the portions of the gcc-4.4.5 build that were giving me issues. I didn't save that information, but I can regenerate it. But it sounds like it's irrelevant now. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
