Yang Tse (2 Jul 2008)

- The previously committed fix for bug report #1999181 prevented using the

  monotonic clock on any system without an always supported POSIX compliant

  implementation. Now the POSIX compliant configuration check is removed and

  will fallback to gettimeofday when the monotonic clock is unavailable at

  run-time.



Daniel Stenberg (1 Jul 2008)

- Rolland Dudemaine provided fixes to get libcurl to build for the INTEGRITY

  operating system.
