--- Comment #6 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-10-07 18:53:53 UTC --- Also, for Jeremy's benefit (since he can't look at the sources), the current configure test is... #include <unistd.h> #include <time.h> int main () { #if _POSIX_TIMERS > 0 && defined(_POSIX_MONOTONIC_CLOCK) timespec tp; #endif clock_gettime(CLOCK_MONOTONIC, &tp); ; return 0; }
