Subject: configure.ac clock_gettime
Instead of always including -lrt when linking with it provides
clock_gettime, only link to it when clock_gettime is not available
without -lrt. This is the recommended procedure. To quote the
autoconf 2.69 info pages:
'AC_CHECK_LIB' requires some care ... it is normally better to
use 'AC_SEARCH_LIBS([gethostbyname], [nsl])' instead of
'AC_CHECK_LIB([nsl], [gethostbyname])'.
