- (dtucker) [regress/Makefile regress/test-exec.sh] Don't try to use test -nt
   since some platforms (eg really old FreeBSD) don't have it.  Instead,
   run "make clean" before a complete regress run.  ok djm.
 - (dtucker) [misc.c] Fall back to time(2) at runtime if clock_gettime(
   CLOCK_MONOTONIC...) fails.  Some older versions of RHEL have the
   CLOCK_MONOTONIC define but don't actually support it.  Found and tested
   by Kevin Brott, ok djm.
 - (dtucker) [misc.c] Remove define added for fallback testing that was
   mistakenly included in the previous commit.
