Changelog
+Yang Tse (29 Jun 2008)
+- John Lightsey filed bug report #1999181: "CLOCK_MONOTONIC always fails on
+ some systems" (http://curl.haxx.se/bug/view.cgi?id=1999181). The problem was
+ that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
+ macro when checking monotonic clock availability. This is now fixed and the
+ monotonic clock will not be used unless the feature test macro is defined
+ with a value greater than zero indicating always supported.
