With the removal of use5005threads, ext/Thread should now be removed as well. Attached is my best effort to remove all references to the ext/Thread and Thread. (The patch does not specifically remove ext/Thread/*. The pumpkin needs to do that.) I noted that Configure silently ignores use5005threads for 5.9.x and later. So if the user does -Dusethreads and -Duse5005threads, they get -Dusethreads and -Duseithreads instead. Is this the desired result, or should use5005threads be flagged as an error? configure.com is out of sync in this regard with respect to Configure. It does not check the Perl version when evaluating the thread settings. Thus, you can still specify -Dusethreads and -Duse5005threads, but I don't know what happens in this case. Whoever maintains configure.com needs to update it following this patch. I cannot guarantee that I have caught everything. I would like to propose that this patch be applied, and followed up with any further corrective patches.Thread Next
