+ * The structure below is complicated, mostly because P1003.1c (the
+ * IEEE POSIX Threads spec) went through lots of drafts, and some
+ * vendors shipped systems based on draft API that were changed later.
+ * Unfortunately POSIX did not provide a feature-test macro for
+ * distinguishing each of the drafts.
