The best way to check if high-resolution
timestamps are available to autom4te is to have perl load
Autom4te::FileUtils and check if that also loaded Time::HiRes.
The problem with that turned out to be that Time::HiRes got loaded from
other system modules, resulting in the test thinking that autom4te used
it when that wasn't actually the case. That's what happened in practice
with your patch.
Hence the current test that merely greps the autom4te source for HiRes,
which is not sufficient, granted. But we have to do something.
Distributions unbundling Time::HiRes ... at some point I don't mind
saying that people have to set am_cv_sleep_fractional_seconds=false by hand.
