Judging from wading through git history, it's mostly just historic accretion from an initial #ifdef __linux__ which was put in by Fabrice way back when configure was barely doing compile-this-code checks at all. Google does suggest that some OSes do provide a CLOCK_MONOTONIC but clock_gettime(CLOCK_MONOTONIC) always fails, eg Centos 3. > Otherwise, you might as well use "#ifdef CLOCK_MONOTONIC" and skip the > configure test completely. Tempting. -- PMM
