If that's actually the case, then there is no point whatsoever in having
both macros in the first place.  Instead of your last patch, just make
everything test HP_TIMING_AVAIL and do away with the "small" distinction
everywhere.

It's only ld.so in which I've made the substitution.  The "large" version is
still used in e.g. clock_gettime and friends.

OK.  The comments could certainly be more clear.
