Comment (by eschnett):
We should strive for uniformity in the default option lists. While different maintainers have different preferences, we should come to an agreement as to how the ET should behave. Us experts can easily tweak everything, so this should be geared towards newcomers on the respective machines.
So far, the arguments (relevant for non-experts) are: (1) make Fortran thorns that use HDF5 work (2) reduce build time
Both seem important. Both also seems somewhat minor, as (1) does not seem to affect too many people, and (2) does not affect correctness. In the absence of other arguments, we should weigh these two. So --
What is the difference in build time on a "regular" laptop, from scratch, with optimizations, for a full ET build with and without HDF5, with otherwise reasonable options (make -j4 or whatever appropriate)?
