Hi John, The variables cause additional checks to be run in configure, which then result in these macros in c++config.h /* Defined if clock_gettime has monotonic clock support. */ #define _GLIBCXX_USE_CLOCK_MONOTONIC 1 /* Defined if clock_gettime has realtime clock support. */ #define _GLIBCXX_USE_CLOCK_REALTIME 1 and /* Defined if nanosleep is available. */ #define _GLIBCXX_USE_NANOSLEEP 1 and /* Defined if sched_yield is available. */ #define _GLIBCXX_USE_SCHED_YIELD 1 I see these defined in include/x86_64-unknown-dragonfly3.6/bits/c++config.h and I also see previously UNSUPPORTED tests now PASS, so I think it's working.
