* libguile/stime.h (SCM_TIME_UNITS_PER_SECOND): Redefine to point to a C variable instead of being a pure preprocessor thing. This has the possibility to break existing compiled C extensions' interpretation of the internal-time-units-per-second, but hopefully there's no too much of that code out there, and in the worst case they can just recompile. Scheme code will get it right without the need to recompile. * libguile/stime.c (TIME_UNITS_PER_SECOND): New local define, and increase to nanosecond resolution if we are on a system in which this is useful and practical. (time_from_seconds_and_nanoseconds): New helper. (get_internal_real_time, get_internal_run_time): New global vars: function pointers. (get_internal_real_time_posix_timer): (get_internal_run_time_posix_timer): (get_internal_real_time_gettimeofday): (get_internal_run_time_times): (get_internal_real_time_fallback): Various implementations. (scm_get_internal_real_time): Return the get_internal_real_time() result. (scm_c_get_internal_run_time): Likewise. (scm_gettimeofday): No need for a critical section, and remove obsolete ftime block. (scm_init_stime): Init all of the new time bases, and decide on implementations of real time and run time accessors.
