+- 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.

- Honour --stderr with the -v option.
o SCP or SFTP over socks proxy crashed
o RC4-MD5 cipher now works with NSS-built libcurl
o range requests with --head are now done correctly
+ o configure script misdetected monotonic clock availability
This release includes the following known bugs:
Lenny Rachitsky, Axel Tillequin, Arnaud Ebalard, Yang Tse, Dan Fandrich,
Rob Crittenden, Dengminwen, Christopher Palow, Hans-Jurgen May,
- Phil Pellouchoud, Eduard Bloch
