What's new:
-----------
- New API: timingsafe_bcmp, timingsafe_memcmp
- New API: dladdr
- New API: getloadavg
What changed:
-------------
- cygcheck and strace now always generate output with Unix LF line endings,
rather than with DOS/Windows CR LF line endings.
- fork now preserves the load order of unrelated dlopen'd modules.
- pthread_cond_wait now acts like Linux and BSD: Resume waiting for the
condition variable as if it was not interrupted, rather than returning 0.
- The internal <sys/_locale.h> header was renamed to <xlocale.h> for
source compatibility with other systems.
- Try harder supporting Netapp drives.
Bug Fixes
